Porn as been the driving force of the net for years as it used to be the only way besides gambling to make any money on the net. We already know now that this is changing - there are actually other ways to make money on the net besides things in the adult industry.
As a reaction to that, you can see the porn industry embracing the latest in technologies to keep making the big bucks, leading to cutting edge technology in their wesbites. This industry seems to have grasped the meaning and possibilities of social networking and user generated content, which is a sensible move I believe.
Latest addition in this category is Pornhorneo (NSFW), a site that aims to Serve The World's Best Porn Videos. But the real innovation is not the fact that they show porn video, but the fact that they show two porn videos simultaneously.When I tried it I was pleased to see it work, although I haven't got a clue why this is appealling.
Go see for yourself, although I wouldn't recommend to check it at work, unless you're in the industry yourself, of course...
