Just check out my latest discovery: the TypePad Bookstore which hosts a collection of books you can purchase from authors who all have blogs on TypePad. I can think of few other endorsements that are more compelling then the fact that authors like Seth Godin, Malcom Gladwell and Steven Johnson all use TypePad.

And if you expanded your search you would find other amazing authors, like Maggie Mason and Julie Powell, blog on Movable Type.
