Strangest thing. My feeds are there. When I click on the link (myblogsurl/feed) it "previews" fine in FF or Safari, but when I choose to add it to a reader (Bloglines or Google) they both give errors. Bloglines says the site doesn't have any feeds, and Google Reader says the last post was in 2006, and I've had many, many, many more since then.
My site is behind a password (a private family site) but if you think you know what's wrong, I can grant a tester account to check it out.
