I've given it a try, and while the amount of content could be higher the quality makes up for it. However the devs are updating the game fairly regularly.
1. The community is pretty damn awesome, growing pretty fast and lots of nice people and from what I have experienced. Based on the forums and in-game the women/men ratio is pretty balanced, although maybe a bit more towards the guys I guess. I'm not sure how many guys play as women, but I haven't really noticed anything. But yeah, ther are plenty of women ^^
2. Not sure on an exact count of how many play, the forum just rached 1000 members but I'm sure it's a safe bet that not everyone that plays the game is registered on the forum, there are always pelnty of people playing though. Some play just for fun and the sex and others are more there for the socializing and roleplaying, or everything combined
The animations are pretty fluid, which usually is the case with mocap so I can't complain about much there. The only thing that bugs me a little is that there are no transition animations between animations and when sitting/standing etc
I'd suggest that you give it a try and see for yourself, it's definetely worth giving it a shot.
