Akismet sucks.

If you have Akismet installed you might be missing out on a few comments. Especially if you have a lot of visitors. Even my username and url I use on blogs with Akismet is marked as spam. Just shows you how something useful can turn into something that defeats the point why it's made in the first place. Just two people can mark you comment as spam and that have Akismet installed and you can forget about commenting on blogs from then on. Because they just wont show.
