Radio vs Blog

So how does Blog compare with Radio UserLand? I started reading Ampersand's Alas, a Blog recently and he highly recommends it.

I bring it up to compare with Radio because it actually lives on the desktop and publishes remotely with FTP like Radio does! Blog doesn't seem to publish RSS, though its template support might be kicked into doing so. (Yeah, I know, it doesn't have an aggregator either, but there are plenty of other programs for that.)
