Who Are Your Top 5 Education Tweeps to Follow?

I know questions like this are insanely hard, but that doesn't stop me from asking them! In preparation for a Twitter for Professional Learning workshop I'm leading at the TCEA Convention in early February, I'd like to know who your top 5 education folks to follow on Twitter are and why.

You might think of it this way: If the Twitter rules changed one day and you could only follow five people in education, who would they be? I'm hoping to get a wide variety of recommendations, including subject specific, K-12, and higher education. There's an "Other" category on the survey, too, because I knew I'd leave something important out!

I would really appreciate your input! Please take a few moments to fill out the form below. And if you don't want to go for all 5, the form only requires that you fill out one. I will be sure to share the results here on my blog right around the time of the convention, so everyone will benefit from your recommendations.

Thanks in advance for your contribution!

NOTE: As of 2/3/13, the survey is closed. But, you can click here to see who my PLN recommended.
