Thing 12: Social Media Sites

Mixx: Interesting. Informative at a glance. Terrifying. For instance the two most popular stories today:
#2: Top 50 Sexpert Blogs
#1: 100 Awesome, Free Web Tools for Elementary Teachers

Obviously, these will not inform the same groups, but might come in handy.

Digg looks similar, I'd hop here now and again.

Newsvine looks like it might be more worthy of a read for more information, and not just a glance at what is attracting the average surfer.

Reddit might be a good combo of newsworthy and interestingly craptastic. I like it.
