Long discussion and some very valid points being made
here on LJ Founder
brad 's journal.
Suffice to say the real issue is not public posts, but private posts. If Livejournal moves hosting to Russia, and the data is "owned" by a Russian company, how secure do you think your private posts will be? I'm glad I don't host my work blog there, I have nothing much to hide on my personal blog, how about you?
Blackmail, mafia, government spying et al... something to consider.
