The Russians don't care about your journals. They really don't.
The people who are worried are Russian LJ users, because the Russian livejournal presence is thriving -- and nearly ubiquitious -- and LJ is seen as a place where you can say whatever you like about the government and get away with it, and Sup has ties to State Security (as almost all successful Russian businesses have ties to the Russian government right now -- things are not clean over there).
No one's going to delete us. They're not going to give a shit about us. But the Russian users have cause for concern, and it's legitimate.
For one thing, almost all those Russian LJ users can remember when the price for writing dissent involved Siberia. And they know it's not that big a leap back to those days. These are people who know just how valuable their freedom is, because it's still pretty new to them.
So, on the one side? The sky isn't falling. All our communities and BPAL trading groups and Superguy discussion places and RSS feeds to Garfield are still going to work.
And on the other side? Don't belittle a people still recovering from decades of harsh totalitarian repression for being freaked out right now. they have plenty of reasons to be scared, even if you or I don't.
