Podcatch -- the latest podcasts from the feeds my friends follow. 

TechBlast -- subscribes to feeds that focus on tech news.

NBA River -- news about basketball.

MLB RIver -- baseball.

There are also two RSS-based Twitter feeds my software maintains:

NYT -- it's been running on and off since 2006, news headlines and links from the New York Times. 

NBA -- the Twitter version of the NBA river.
