You jogged my memory and I downloaded it, after a small detour trying to find a version that'll run on my 11YO iMac. I have a whole collection of feeds alread, which I have no knowledge of at all. Many I've never even heard of. Is this a default thing, or was I accidentally bookmarking RSS feeds or something years ago and never knew?
