A post with no title is a perfectly good RSS item. The spec says all of an item's
elements are optional, provided at least one of title or description is there —
so this one goes out as a <description> and nothing else, which is exactly how the
linkblog end of the feed world has always written.
Worth knowing if you have ever tried to link to a single one of these: we always
publish <guid isPermaLink="true">, so this note has a real URL even without a title
to hang it on.
