Alternatives
So, I'm looking in to pyBlosxom, because development on blosxom itself seems to have dropped off to basically nothing. The comment spam issue is still my top complaint, so I'll keep looking until I find something good.
In the "Alternative to Facebook" department, I've been looking at OneSocialWeb, which seems interesting. It's more of a jabber-based thing (xmpp, technically), but I like the way it looks. Check out the video on the website for a good introduction.
