Thanks to Al Delgado for the tip on this. There's a big education bloggers shindig in San Francisco November 22-23. Sounds like it will be quite a gathering.
I hadn't heard of (or if I've heard of it, I promptly forgot about it) the EdBloggers Network. K-12 focussed, with colleges of education participating.
I'll be keeping an eye on this group... (no, not in a scary restraining-order kind of way...)
