For the most part, I enjoyed this blog tour. It was organized differently from what I'm use to but it was interesting. I think we hit some rough patches but it seemed most of the authors had fun.
I can't say that I really learned anything from it, aside from all the different perspectives different authors bring to the same questions. It was fun to read all of the different points of view.
I didn't sell any books during the tour because mine has been released yet. I didn't buy any, either.
With a few modifications (which I don't want to talk about on such a public forum) I'd contribute to the MSH blog tour again.
