CompleteVideos(.)com for a tube site.
ByYou(.)com for a social network (I envisioned it as encompassing a tube site as well using subdomain Videos(.)ByYou(.)com, can have others like Music(.)ByYou(.)com, Articles(.)ByYou(.)com, etc.)
Shizzles(.)com for a social network too - I even designed a logo and somewhat of a front page for it too if you'd like to take a look. Pretty apt for a truly cool network unlike the lameness of MySpace and Facebook.
Icia(.)com is another possibility for a video site - probably more apt for cam though as it sounds out "I see ya". Stretch as that may be, it's a nice short pronounceable made up word or brand name and would easily be branded.
That's probably the best I have for social stuff. Shoot me a line if any of them interest you and I'll quote you prices. BTW, what happened to your JLH av?
