We ought to be thinking about a filtering system for feed readers based on loose instructions written by users, and shared on the web, to be parsed by our AI. Design your personal algorithm with AI engine. Share the good ones with your friends, and have it work on the web, in any feed reader. There are ways to do that. If you're working on such a project, let's hook it up to FeedLand. It does a lot of feed reading, and has a nice API for downstream feed readers. It's a good place to put an AI-based filter.
