No idea what it'll mean on our end, however.
EDIT: Nothing much will be changing, I suspect. The guy who owned livejournal will still be round, the community base will staying the same... See what is said here. I'm figuring there is no hassle. Shit like this happens every day in corporate worlds, and Six Apart appear to be fair enough. But, y'know, time will tell, and so far I've been happy with the livejournal choices made, and I've no reasons to think this'll be different.
This is from Six Apart.
