For further reading, check out these three fine blogs (with a bonus fourth that'll certainly grow).
E.D. Kain - Forbes actually lets this guy write critical stuff! It's not entirely focused on education, but he gives a good deal of space to edu-topics.
School Finance 101 - Rutgers Professor Bruce Baker. Check out hilarious (and insightful) overview of the Dumbest "Real" Reformy Graphs and A trip to the Reformy Education Research Association. School Funding Deception Alert! (in a CAN) is a more pointed look at some really questionable stuff from a reformy group.
Junk Charts - I'll admit it: this was a pretty recent find. But Kaiser Fung's takedown of Bill Gates' crap chart is not to be missed. Very little of it focuses on education, but it's still fun to read.
A "Fuller" Look at Education Issues - Ed Fuller's brand spankin' new blog. There will certainly be a wealth of interesting posts.
