I'm not going to press new folks to go join Facebook in order to try this out at this point, because I think it's time to deal with the LiveJournal integration. I'm going to try to do that in the next few weeks -- once that's done, you should be able to simply sign into CommYou with your LJ credentials, and it'll pick up your flist and stuff automatically.
But for folks who are already using CommYou: come play! The new functions are intensely experimental, but I've gotten it to the point where it's starting to feel right...
