kc dyer has a brand-new book out: A WALK THROUGH A WINDOW. She's started up a nifty-cool blog "written" by the main character, Darby Christopher. Check it out. (kc dyer blogs as herself here.)
I think this is just about the neatest way I've seen the blogosphere used by an author. kc has just set her character loose from the book's bindings.
In order to allow a character to have her own blog, I think she must have enough life that she can leap off the page. Now, is that literally, or virtually?
