I have a Deadjournal (sorry no link
) and I love it. All the upside of Livejournal, without the outages or slow pages. But, you have to know someone who has one. Sorry, I used my invite a long time ago and it's gone farther than I can track it.
I also have a LJ account but it's mainly for commenting in other people's journals. And I just joined the FIRST community.
I came close to switching to blogger the other day. They look so much nicer compared to most people's LJs.
And, as Brandon said, Wordpress.
