I certainly don't think it is because anything is wrong with Maine -- they're a leader in K-12 ed tech. You could ask the same question about other innovative states like Indiana, or for that matter, innovative schools like High Tech High or The Met.
It is an important question though if you want to understand the lack of zip in K-12 ed-tech blogging.
Update...Stephen points out that I am on crack. Bob Sprankle is from Maine, as is Cheryl Oakes. Those weren't intentional slights, I just didn't know they were from Maine. Also there is Learning in Maine.
But addressing Stephen's second point, one would think that working in a Maine middle school in particular would give one a lot to blog about, since those schools have had 1-to-1 laptop programs for what, five years?
