1) Old entries are hard to get to: “back n entries” works only for a while, after that you need to go day by day. Which makes paging through a blog that is not updated daily a nightmare.
2) Can’t run ads.
3) The degenerate “friends” system with it’s stupid add/remove politics. It’s better to read stuff in an aggregator.
4) Livejournal is widely known for drama and teenage angst. Having a Livejournal blog is similar to having an AOL email – it doesn’t matter that the famous hacker JWZ has one. People will still think that you are a loser.
5) No categories. You have to keep a separate journal if you want to give your readers an ability to read only stuff that interests them. I want to write some entries in Russian, but do not want to have a separate journal for that. Also some of my readers might be interested in my photos, but not in what I think about Livejournal.
6) Constant outages, lost posts, slowness and other technical fun. What else can you expect if you share your servers with a million teenagers frantically refreshing their “friends lists”.
7) No trackback.
8) Image hosting that is still in beta, but a fully released “phonepost” system that instead of using MP3 format uses OGG. I spent a couple of hours trying to find a player that would actually play these files when I click on them, but for the most part miserably failed. Those are a couple of hours of my life that I’ll never get back. I mean, what the hell is wrong? You click on a file, the player opens, but doesn’t play anything. You click play button – nothing. You click again…. Arrrgh, it’s driving me nuts!
10) If you set an article with a future date in Livejournal, instead of showing up if your readers lists normally, it sometimes disappears. There’s a bug there somewhere.
Livejournal does have a superior comment system, but since I don’t get too many comments it doesn’t matter that much.
Did you expect the Spanish Inquisition? No? Well, nobody does. But it brings you 11th reason:
11) No integrated search.
