RdSplay

RdSplay is my RdMise-based feed reader. You can see it in action on this site.

It's very much a work in progress, though I've already gone and given it a version number. The current code (1.2):

• Parses RSS2 and Atom for titles, GUIDs and links.
• Resolves relative URLs in Atom feeds with xml:base.
• Understands that the same item can appear in many feeds, though at the moment it trusts all feeds to get their GUIDs right.
• Records read/unread status.
• Supports hidden/disabled feeds:
  • Feeds that fail repeatedly or return HTTP Gone are disabled automatically.
  • Items from hidden feeds are always hidden.
• Updates the feed URL when it sees a Moved Permanently response.
• Lets items be "starred" as interesting.
• Outputs recent item Atom feeds and OPML™ subscription lists.

but it doesn't (yet):

• Support relative URLs that don't use xml:base.
• Attempt to understand content of items at all (fun!).
• Have tags or other annotations for "starred" items.
• Include search.
• Have a scraping mechanism for sites without feeds.
