Cue the conspiracy theories.
Will it be better? Will it be worse? Everyone is saying the right things, anyway -- they're setting up an advisory board that will include two actual LJ users "elected" by the community as well as brad; developing a clear and consistent policy about "appropriate content" is a priority; all development and servers will remain in the United States (a key factor for privacy and security issues). Of course, it's one thing to say the right things and another to actually follow through on them. And the owner of SUP is apparently a crony of Vladimir Putin. So, as usual we will have to wait and see.
Brad, LJ's founder, who has been publicly critical of 6A's moves in the past, seems to be on board. I find that more encouraging than otherwise. I wish I read Russian; it would be great to be able to read the reaction of the Russian users on my own, and to get a sense for the breadth of them, rather than having it filtered through someone-or-another's agenda.
