WordPress
I've set up a WordPress blog here:

What do you think?
(Yes, I realize that it's not a link you can click on. This is
because the text editor that Community Server uses doesn't support
creating hyperlinks when used with Firefox. This is another
reason I want to switch. Not that this problem is insoluble, but
I'd rather use a tool that doesn't have these kinds of potholes).
