Grey area blogging?

So I've been thinking of starting up a separate blog that covers some of the more 'grey area' stuff, so I'll have to do some self-hosted thing should I go forward with it. I already have several domains that I could use for it, so getting that taken care of is not a problem. My only real issue would be what content management system I should use for it. I know there's wordpress, but what else might be out there for me to use?
