If you haven't been there yet, its about time!
There is not much text on the front page. Instead you get a lot of big thumbs of high quality videos. Everything is free at Shameless.
The player of the videos is much bigger than on other tubes, so you will see just a bit more than anywhere else. Also you get categories, tags, a decent description and you can vote on content.
Most of the videos are shot in HD and actually only homevideos and "older" videos have a lower quality, but thats just the nature of the thing.
