For those who are unfamiliar with Pandora, it’s a revolutionary personalized internet radio service that helps you find new music based on your old and current favorites. Users enter a song or artist that they enjoy, and the service responds by playing selections that are musically similar. Users provide feedback on approval or disapproval — which Pandora takes into account for future selections.

What are the current methods of discovery for new porn? You have to click and browse, click and browse, and constantly repeat this intriguing yet unnecessary process. Instead, I want an application to constantly serve up porn that neatly aligns with my fetishes. I’ll give each video or picture a thumbs-up or thumbs-down, and the algorithm would adapt to my ratings.

Where is the revenue model? Once you can whittle down to the user’s core fetishes, hit him with a laser-targeted advertisement. The probability of conversion just increased by 120% (a hypothetical but realistic number). Ask any adult webmaster and he’ll confidently tell you that niche porn sites make the most money.

As more and more fast-loading, high-quality porn tube sites emerge into existence, they have made a powerful impact on the industry. On the upside, the adult industry is now embracing rather than fearing this new technology. Porn companies are quick learners, and they have learned that DMCA takedown notices are a temporary and ineffective solution. On YouPorn, there are now teaser videos uploaded by the companies themselves with obvious watermarks and banner ads on the side. All of RedTube’s videos are approved and sponsored by companies like Twisty’s and Brazzers.

XVIDEOS is a relatively newcomer that is rapidly gaining market share. Take a look at the following Alexa statistics.

What’s the difference between YouPorn, RedTube, and XVIDEOS? Check out our assessment of the three sites based on the following factors.

Quality

As its tagline states, XVIDEOS is really “BIGGER and BETTER than the others.” XVIDEO’s minimized video screen is 615×480 pixels versus RedTube’s 580×455 pixels and YouPorn’s 600×480 pixels. The difference is minimal, but XVIDEOS is the technical winner in this category.

Speed and Availability

Buffering sucks. YouPorn has done an amazing job with scaling its media delivery servers. Buffering is nearly instantaneous (on our internet connection) and the new playback-skipping feature is useful. In this category, RedTube is decent and XVIDEOS is horrible. XVIDEOS momentarily freezes up the browser when you attempt to skip to a different location in the browser.

Content Variety

XVIDEOS has a huge number of new videos (100-200) added to the database every day. YouPorn and RedTube manage to add about 15 new videos on a daily basis.

Concerning niche variety, XVIDEOS wins again. Every variety of porn you can think of is available. Check out the XVIDEOS tag cloud to see what I mean. YouPorn has a fair mix of amateur and professional porn. Then RedTube is mostly production-quality porn

Filtering and Discovery System

YouPorn allows you to filter by Newest, Top Rated, and Most Viewed. Each of these categories are able to be further filtered by time frame: today, yesterday, this week, all time. YouPorn lacks a content filtering system like RedTube, which offers Channels for Amateur, Asian, Anal, etc.

XVIDEOS combines the best of both worlds and offers Best Videos based on time frame, Most Hits, and then dozens of niche tags to narrow down the collection to your liking.

Overall

YouPorn is the winner in overall user experience. It offers the best uptime and speed while keeping a simple interface. XVIDEOS is dumping a massive amount of content onto the web, which is great if you’re looking for dozens of new discoveries daily, but it is turning into a huge mess.

Redtube, one of the most popular porn tubes, was hacked today. A Turkish hacker group called NetDevilz defaced the front page of Redtube, leaving their logo and a message that says “No Porn!!! We’re not first but we’re the best.” See below for a screenshot.

We’re interested in learning what was exploited in the tube script to gain access to the Redtube servers. This vulnerability may be present across hundreds of other porn tubes. More on this later.

So is this the final version of Porn.com? The layout and theme still look the same as they always did: awkwardly clean and minimalistic for a porn site. The content is the same too, but I noticed a couple of changed logos and graphics within the categories. Anyway, the company behind Porn.com did a great job making an up-to-date version of the one-stop porn portal with the most expensive domain name ever.

We are still waiting for another top adult industry domain name Sex.com to launch its website. Sex.com seems to be in private beta, whereas Porn.com opened up its beta website to the public to test.

Rapidshare calls itself “1-Click Webhosting” and boasts “210 Gigabit/s of Internet connectivity and 4.5 Petabytes of storage,” and it is one of the most popular online channels through which porn is pirated. Users can upload huge files like DVD rips and zipped up picture galleries to Rapidshare and allow others to enjoy fast download speeds. There are extremely active forums like Lawina Board and PornWz that are dedicated to posting Rapidshare links to high-quality, full-length porn videos.

You would agree with me in saying that Boobik is an odd name. If anything, the word “boob” suggests that it is an adult-themed website. But I wanted to know if the name has a meaning. Boobik replied that “Boobik” is a nickname for a loved one, like the common words “honey” or “darling.” I never heard of this before, so I guess Boobik is trying to invent new slang.

As far as features go, Boobik is not merely an uncreative clone of Twitter. Boobik allows you to write 3 different types of posts: text, picture and video. You can directly upload a photo from your desktop or also copy & paste video embed code from a porn tube. This is an essential feature for a NSFW microblogging service because it allows members to share porn in a fun and easy way.

Another cool feature is Boobik can notify you via SMS or IM when someone you are “spying” posts something new or someone comments on your posts.

Boobik has a lot of potential as an emerging Porn 2.0 application. The creator promises personal messages, chatrooms, and a full-fledged API in the near future.

There are still some major kinks that the Boobik team has to work out though. I am using the standard Safari browser, and the AJAX in the signup script did not respond after I clicked submit. Also, I continue to get timeout errors while browsing the site.

Let’s also hope that the Boobik design gets revamped. That interface is blocky and ugly while the harsh orange color just stings your eyes like citrus juice.

Meanwhile, I plan on using Boobik for EroEvo in the same way mainstream bloggers use Twitter. Follow me on the EroEvo Boobik page.

EroEvo: First, we’d like to know more about the genius behind this revolutionary porn search engine. Can you give us a brief bio and discuss your background in software development?

Aidan: I wouldn’t say EveKnows is a revolutionary adult search engine so much as an evolution in porn search technology. My background is in software usability, so with EveKnows I’ve tried to take the best elements of various search engines and cobble them together in a way that makes them intuitive for people to work with. I have a degree in Computer Science and a love for making computers easier to interact with; in fact, easing human-computer interaction has been my goal since the late ’90s. EveKnows is something of an experiment, in that regard. It seeks to create a friendly, easy-to-use, free porn site that anyone can use without fear of viruses or other malicious software.

EroEvo: Your search engine is named Eve and your crawler is named Caroline. Is there a significance behind these names?

Aidan: I like the idea of personalizing software, which is why the site has a human name in the title. The selection of ‘Eve’ over other names was mostly because I’d recently watched ‘All About Eve’ and thought it sounded cool. ‘Caroline’ actually does have some significance; it derives from Caroline of Brandenburg-Anspach, who corresponded with Leibniz in the early 18th century. Yes, I’m something of a history nerd.

EroEvo: From what I’ve seen so far, EveKnows is the best porn search engine on the internet. What gave you the idea to start the monumental task of creating a web 2.0 porn search engine?

Aidan: Thank you! Search technology has interested me for a while, but the success of Google has, I believe, rendered other general-purpose search engines redundant. Thus, I wanted to create a niche search engine. I ended up picking porn searching because it seemed under-served and the adult industry has historically had a reputation for being a dark, unfriendly corner of the Internet. Attempting to create a site that was friendly, inviting, and intuitive, given those constraints, seemed like a neat challenge. Of course, it also helped that at the time, I had no idea how much work would be involved.

EroEvo: It seems that you programmed EveKnows in Perl. What are the advantages and disadvantages of using Perl for a search engine, and would you recommend it for others?

Aidan: The website interface and search spider are both written in Perl. Perl was designed for easy text processing, which makes it uniquely suited for search engines. The actual search engine back-end is written in C for fairly obvious optimization reasons. That language combination has worked very well for me, but I’m sure you could use other languages with equal success. PHP or Ruby could have been used for the interface, and the spider could easily have been written in just about any scripting language that includes HTTP support.

EroEvo: What is the biggest challenge in creating an algorithm for a porn search engine?

Aidan: Without a doubt, the biggest problem is categorizing each gallery. Users are interested in the photos and movies, but I can only efficiently index text. If the text isn’t accurate, the search results will be very poor. It took a while to find an appropriate way of balancing incoming text links, gallery titles, and embedded gallery text to give accurate search results.

A similar problem is keeping malicious web sites out of the search results. At its simplest, that could mean rejecting any galleries with iframes or scripting; this approach, however, ended up in missing a lot of safe galleries that used JavaScript for mouse-overs and such. Finding a metric for judging the safeness of a site’s JavaScript was a pretty challenging task.

EroEvo: Without any pay-for-placement links in the results, how do you plan on generating enough revenue with EveKnows to make a profit?

Aidan: There are banner advertisements beside the search results and sponsored text links below the ‘Popular Searches’ section of the main page. Obviously I don’t want to throw too many ads on the site, and this formula seems to strike a decent balance between keeping the site clean and keeping the server funded. I believe it’s incredibly important to not risk the integrity of the search results, so pay-for-placement can never be an option.

EroEvo: What is your future outlook (near and far) for EveKnows?

Aidan: I’m always playing around with the code. Usually that means adjustments to Caroline so that she finds better galleries, which results in better searches. In the longer term, I’m working on adding the ability to search more types of media than just photos and video clips.

WikiPorno is working hard to improve the knowledgebase despite the fact that user-generated content is more difficult in the adult industry. Surfers have the tendency to look out only for themselves and their horny penises (or vaginas). So there goes the good samaritan right out the window. Don’t help your neighbor who is looking for the same stuff. By the principles of economics, the people who mainly contribute to these Porn 2.0-type websites are those who have a financial incentive. Which can be summed up as webmasters and affiliates. They do corrupt the results, and you are the solution to this problem. We users outnumber the webmasters, so our contributions can overpower theirs.

The power to change the status quo of WikiPorno is in your hands. Share your expertise by writing an article on WikiPorno today. Get started by working on some of the Wanted pages.

Fusker kills the concept of serving free content alongside advertisements for sponsor websites. Doesn’t this sounds like the business model that TGP webmasters live off of? “Kills” is probably an overstatement though. You have to be a bit technically savvy to even use this Fusker technology. So the newbie or average porn surfer will be confused when confronted with a Fusker interface.

Anyway, Fusker’s learning curve is not that difficult and it is a great idea. You can type in a gallery url that is slightly modified with Fusker syntax to extract the target images from their source and display tham on a new webpage. This means you can have a clean display of all your favorite TGP pages like this and this.

Fusker works because we tend to number our photos in increasing numerical order. For example, in a folder, there would be pic1.jpg, pic2.jpg, pic3.jpg, and so on. Fusker takes advantage of this by looping through those expected numbers. Here’s a description of how Fusker works from Wikipedia:

For example, if you go to a fusker web page’s form and enter the text http://www.example.com/images/pic[1-16].jpg, the fusker technology would produce a page that displays all sixteen images in that range, from http://www.example.com/images/pic1.jpg through http://www.example.com/images/pic16.jpg. It is also possible to use lists of words by writing http://www.example.com/images/{small,medium,big}.jpg which will produce three urls, each with one word from the bracketed list. The web page is then presented to the person who did the fusker, and can also be saved on the fusker web server so that other people may view it.

Fusker also works for grabbing a bunch of personal photos from private personal galleries. Although legally questionable, this is a powerful tool to hone in and steal fresh amateur content. Photobucket galleries seem to be especially popular like this and this.

The following is a variety of websites that offer Fusker technology. These types of websites are rapidly getting shut down because of obvious copyright infringement issues, so let me know if you discover a new Fusker or see a broken link.

• FuskerFind
• Sexmit
• FuskerBytes
• Fuskem

To complement Fusker, you can use a tool called Text Control Downloader to easily download a set of photos that you find. Just like Fusker, TCD loops through the url syntax to download a set of pictures to your desktop.

Fusker websites are still pretty primitive. The search functions are especially basic with a lot of room for improvement. Also, they can be more user-friendly by adding social bookmarking and networking features. Elements like tagging, comments, and upvoting can help sift through the heap of links on these Fusker sites.
