When I think "porn for geeks", I think videos in which the slider is labeled by "act", so you can skip over the stuff that grosses you out (like watching blowjobs), or even avoid videos with that stuff altogether and zero in on videos that have the stuff you like in the largest ratio. I'm not a developer though. Sure, I threw together a tumblr site (http://lookAtThisFuckingSideboob.com), but I think it would be fun to help build and grow a proper [porn for hackers] site.
Yeah, me, too. Some kind of similarity metric would be nice, wouldn't it? "More like this"? Email me if you want to get serious any time.
