Because I have several friends who are using it, I asked Brian for a LiveJournal account (only active LJ users can bestow free accounts), and he gave me one today.
This gives me the power not only to have my own, but more importantly to be able to post comments with my name on them. LiveJournal doesn't stick a regular name field in with comments; you're either a registered LiveJournal user (you can't get a free account without an invitation, and invitations are limited), or anonymous. Better still, it gives me a page where all of my friends latest entries can be read. That alone makes it worth the trip.
I like some of the things LiveJournal offers (that friends page rulez), but it has certainly reminded me of one major drawback about Blogger (and the reason I ended up switching to Greymatter a while ago): being at the mercy of someone else's software (in particular where it comes to speed). Yes, I have a shared hosting account, so to some degree I'm always at someone else's mercy, but I like having my blogging software on my server. I control it completely, and it's a lot faster than the often-slow LiveJournal servers. That's not their fault, they just have far more users than my host does, and those people are hitting LJ's servers much harder.
I'm going to enjoy LiveJournal, but I really enjoy doing things myself too.
