I used to think Twitter was worthless, but I totally get it now. I don't follow friends so I can hear about what they had for breakfast, lunch, and dinner, but I do follow sports journalists, comedians, mainstream affiliate companies and affiliates, etc. and I get a ton of good information off there. I find myself on my iPhone Twitter several times throughout the day...

Nice info - Twitter is a pool of information.
