It's true it's disappointing to find those common misconceptions are there.

But it's even more true education is sometimes -yes, sadly- a really firm structure against changes. Just an example: imagine a Ph.D. thesis talking about using WordPress.com in education with lots of examples, work field, and even a stunning online site to be reused by other teachers. You should constraint that to a printed old-fashioned impossible-to-read book-like thesis. :)

(I remember a nice post from A. Spittle related to that: http://andrewspittle.com/2009/11/22/my-case-for-moving-beyond-a-printed-senior-thesis/)

A huge methodology and conceptual change must take place in the educational world, involving learning communities, horizontalization, and openness to support efforts like the introduction of WordPress.
