For those arguing that Live Journal isn't dead, I don't see you arguing that it's necessarily alive either. It's a ghost of what it used to be. Therefore, I'd like to propose what it is now is 'Zombie Live Journal'. You can argue that it's alive and win the argument. You can argue that it's dead and win too. It's Zombie Live Journal.
I went over and read brunorepublic's treatise on the whole thing because Jeb/50poundnote commented on it. I agree with his assessment, and wish I had read him back when this was the social network. I wrote a lot of my thoughts here but it was the commentary I got on them that kept me doing it. I changed my opinions on many things because of thoughtful discussions I had here, and although I stuck around for a long time after the "exodus", I ultimately stopped when that dried up. Yes, I miss the writing and creativity, but the commentary will never return.
