AllTop

Not sure if you're familiar with Alltop, but it's the creation of Guy Kawasaki. It's a great tool to use for research, general knowledge, or even just killing some time.

"Alltop is an “online magazine rack” of popular topics. We update the stories every hour. Pick a topic by searching, news category, or name, and we’ll deliver it to you 24 x 7."
