News Aggregator

Perhaps in response to Ezster's CT post about web-savviness marking the new elite, I'm finally going to install a news aggregator. There's also that additional factor of needing to stop spending so much damned time surfing around. It's about time.

Wikipedia's list of available feed readers is quite daunting. Since I'm very happily running Firefox, I was thinking about going with the mozdev community feeder, Habari Xenu. Then again, I still don't know enough about running a feed to make much of an informed decision.

So. Any advice? Do you use an aggregator? If so, which? Which should I avoid?
