A long, complicated project of mine (under the direction of Peter Suber and the auspices of the Harvard Library Lab) is nearing its release date – TagTeam (source, demo site).

TagTeam is an RSS/Atom/RDF aggregator that allows administrators to remix and republish feeds on multiple levels. It also allows for the filtering of tags – additions, substitutions, and removals in a flexible “tiered” filtering system.

It uses the feed-abstract gem I wrote to create a “common object graph” between the different feed formats – this has been a huge time saver and made feed parsing much more reliable.
