Please welcome my colleague and mentor Tonya Arnold to the blogosphere. It sounds like while she won't be writing exclusively about education, readers will luckily find it in the mix. From having worked with her, I can recommend those posts unreservedly. (I'm sure the others will make for good reading too.)
I also have yet to mention Dusty Humphrey, who teaches across the hall from me. Daily he invites students into lively, spirited, and enlightening discussion and debates on the literature they read. Be forewarned: if you work for The Man, reading his posts could result in your head exploding.
