Livejournal does everything I need it to. Some of it may be a bit of a kludge, and technically inelegant, but it does what I need - provide a space for me to blog and read other people's LJs and RSS feeds of other blogs.
I don't want to have to learn my way around a new system. I know this one. I probably use it in a slightly idiosyncratic way, because I've been here a long time and some things may have changed but the way I use LJ hasn't. So a new 'better' system might be actually less user-friendly to me, even if it were more intuitive to someone coming to blogging afresh.
I don't want to start building a whole new social network in a new place. OK, so many of my 'friends' on LJ probably don't give a toss whether I live or die - hell, that's been proven enough times. But at least I know where to find them.
The name. Dreamwidth. Who came up with that, and do they have a pendant with a rainbow unicorn on it? Or were they looking at their brand new dildo at the time? (actually, that'd be dreamgirth...)
The mission statement. "Dreamwidth Studios is a home for creative artists of all types." Pretentious, toi? Je fuckin' pense, aye. I'm not a 'creative artist' - well, not most of the time, anyway. I'm smart, occasionally funny, sometimes angry, often political and OK, once in a while, creative. But most of the time I blog about what's going on in my life. And I don't want to feel unworthy of being part of a community because of it.
