The "Latest Polls" page of Real Clear Politics lists, day by day, the latest local and national polls related to the Presidential election. It's almost a masochistic exercise - the polls move up and down slowly, and we have almost two months to go - but, I'm addicted.
Facebook - Yes, I am one of the 100,000,000 million with a Facebook. It's all about social networking - but that's a term changes as the sites evolve. What's it do for me? I dunno!
Linked In - This is a site that's more of a business-oriented networking site - it's more about professionals keeping up with each other. I visit here less often, but its useful to keep track of my professional colleagues.
I also check CNN.com on a regular basis - and I look at the New York Times daily - on my Iphone. That's a whole different category. I also check in with Apple.com - the site that supports my computers, Iphone and Ipod - and helps explain how they all work together.
Finally - yes, I admit it - I like to browse YouTube - I like to think of it as America's Funniest Home Videos - unleashed! Plus, I can also get it on my Iphone!
