This reminds me of one of my favorite Mac apps ever, Feeder:

Literally, the only app I miss after leaving the Apple ecosystem.

The question I always have is how to keep a permanent archive of entries for long-running publication histories. You don't want the feed to grow without bounds, so paging (by time period or sliding windows of X entries) seems useful. Atom feeds have RFC 5005 links. I don't recall such for RSS 2.0, but it wouldn't be that hard to extend, I guess.
