I like MovableType (the software I blog with), and I like Six Apart, the guys who created it. It's a good piece of software and it has a great support community that got me up the fairly steep learning curve in the early days.

I like them a bit more now, because of their creativity in putting together TypeKey. This is largely a response to the blight of "Comment Spam" (the burden of phoney comments made to weblogs simply to highlight porn and viagra websites).

On the face of it, it seems a highly creative solution to the problem of spam comments that is a doddle for bloggers and commenters alike. One, once-off registration and you're done. And lots of flexiblity in setting the rules for each blogger. And another solution that seems to show a deep understanding of the power of community.
