Makes me sad, because Dreamwidth hasn't got all the communities I liked on here, but then I've noticed a slow downwards trickle of posts in them anyway.
I liked LiveJournal because it was LiveJournal. I don't use the other sites because the "populations" are lower or they don't have the functions I liked. But then, it's been known for a while that the new LJ staff don't give a shit about their existing userbase; they said as much in an article a few months ago. They're just covetous of Tumblr's customer base (or Facebook's, or Twitter's, or etc).
