I've been working on this for a while now, and finally my blog has a functional RSS feed. It's the super-ghetto RSS2 format, rather than the newer, slicker (and more complex) Atom, though, so nice things like, I don't know, HTML(!!) are a no-go, and it's not even W3C standard compliant, but it works with my RSS reader which is good enough to start with. Use at your own risk.
And not to worry, someday I'll do this properly and set up an Atom feed.
