Niche news aggregators and other monitoring tools

A few news aggregators you may be interested in but may not have known about. You know about Google News, but do you know about: 

Not an aggregator, but worth mentioning:

While on the subject of monitoring, you undoubtedly know about Technorati (which seems to arbitrarily ignore blogs linking to MountainRunner), but do you know about:

  • Blog Pulse by Nielsen to explore trends and track conversations
  • Talk Digger self-described as "the best way to find, follow and enter conversations of the Web".

Talk Digger is interesting, but if you're reading this blog it is probably not tracking the conversations you're interested in. BUT, it's still worth exploring. Maybe if we ALL jump on board, it will become useful in tracking discussions related to participation in the global information environment.
