This is a win-win, in my opinion. I might even sign-up for a blog tour myself. We'll see how it goes with being a host.
I'll add a block on the right hand column with the writers I'll be hosting.
I will tweet when the authors appear on my blog.
My blog already shows up on Facebook, MySpace, and Amazon.
Check out Goddess Fish and see if you'd like to signup for hosting or guesting a book tour.
