In case you just landed on Earth, Twitter is a tool that feels like part chat room, part news feeder, part network marketer. Seriously try it out with a browser addon, and check the public channel to find interesting tweets.
I suggest grabbing twitbin if you use Firefox. It creates a side window that's getting a constant stream of updates. Unfortunately, I'm still new so I'm learning tweeter netiquette. You can follow me at VictusFate I'll follow you back :D (and I'll keep following as long as you don't spam me about how to get rich via flying carpet sales and black magic)
I added some of my favorite Twitter tools/applications/websites to my web marketing tutorial
Of course I just came across this twitter segment from the Daily Show:
