Filtering. I already subscribe to many of the currently archived feeds. I'd love to be able to filter those out of the RSS feed. Since RSS retrieval is a simple GET, the list of filtered feeds would need to be stored on the server side. Or you POST up the list of filtered feeds and get back the filtered aggregate RSS. Aggregating and archiving RSS seems to be hot right now, so a standard mechanism for filtering would be appreciated. My vote: lets expose a web service to retrieve aggregate RSS information.

I posted yesterday about wanting a filtered version of aggregate RSS feeds. I take it back! I want my RSS news aggregator client to be filter enabled, not the service providing the aggregate feed. What was I thinking? Since I've signed up as a member of RSS Bandit (and just got accepted as a member of Harvester) I'll look into adding the feature myself.
This is precisely what I want. I'd love to use the SharpReader interface or a web-based interface and get the same aggregated feed, including what I've read already.
Maybe with Harry joining the various workspaces, we'll see something similar soon!
