I can't predict the future, and I know some people are leaving, but as far as 1.0 went... I liked the community. I'd occasionally blacklist some people, but I have no patience for shout spam. There was only one person I kept on there forever, which isn't too bad considering. :P
I don't know what it's like elsewhere, but I didn't have any interest in seeking a new server. Hyperion's home. Population seemed okay to me, but going by what I've read elsewhere, it was considered one of the lower populations.

The "legacy" servers should be open this weekend, so drop in and get a feel for yourself. You'll find good and bad on any server, really.
