Looking for more good education blogs

You can peer at random people's subscriptions on their blogs, but I need to do some actual work before Christmas. So, what's a bigger shovel?

• Educational bloggers on Flickr – pond a bit small, fish are self selecting
• Bloglines subscriptions of famous people, like "dnorman" – D'Arcy Norman presumably – enormous pile, lots of good quality
• Edublog awards nominees
• The map of edubloggers (self-selection again) powered by Frappr! and Google Maps
  

• any more ??
