Most surfers seem to be going to the tube sites now... I know most people dont trust alexa too much, but this graph speaks for itself:

youporn and redtube are two of the most popular adult tube sites now. You can see the hun and worldsex are in a slow decline, while these tube sites are shooting sky high, almost 2 percent reach, in less then a year. They get so much traffic they dont know what to do with it.
This business is getting harder for most people these days following the "old" model of running a tgp and submitting galleries, but talk to someone running a tube site and I bet they will sound like business has never been better. I havent wanted to start one because of the crazy bandwidth it would take, the copyright problems, and all the other legalities that come with allowing surfers to upload stuff. But its hard to ignore the amount of traffic they get, it makes the big tgps look tiny by comparison.
