Thanks to more help from Jasra, we dug up a Moveable Type template and installed it into Planet Geek's configuration. I just updated to the new template after testing it out a little using Bloglines,and it appears to be presenting stuff correctly - there should be Comments links and the 'Read more..." function should be working. I'll throw a cut here to make sure.
So, let me know if this makes any more sense, or is easier to deal with!

I'll go fix your feed for you. :)
Ok, the feed should be fixed now. I'll keep an eye on it to make sure. I/you/we might need to move the stuff in the [content:encoded] tags up to the [description] tags.
