Does school 2.0 need an affirmitive action program?

Seventeen years ago a few months into my first teaching job, I was standing in an assembly when I realized something.  I was the only white dude in the room.

I was looking around Twitter today at who other people follow and I had the same feeling come back.  There are only white dudes in the “Twitter room.”  I could not find anyone who was not.  Out of every class that I have collaborated with this year only one person was an African American. Then I thought about the blogs I read, the wikis I check out, and the podcasts I listen to.  Same deal as the Twitter room.  What’s up with that?
