Third Linkfest
As I write this, I’m sitting in a hotel room in New Orleans. My girlfriend and I flew down here so she could attend the AERA conference, a big conference in education. It’s nice that it coincides with a big festival in the French quarter. It’s been a lot of fun checking that out. Even if you aren’t here to check out the festival, you can at least check out some cool blogs. Below are the items I “starred” in Google Reader in the past couple weeks. Hope you get as much out of them as I did!
