I just received an email from Sam Houston at Book Chase asking me to help spread the word about his silence. Blogger has somehow mistaken him for a spammer (the result of some software program) and has locked him out of his blog.
Sam has posted comments on many blogs -- he wants the book community to know about what has happened so people will realize that he has not simply disappeared. He is trying to get an interview with a real person, but doesn't know how long it will take to get it straightened out.
He has no access to his blog at present, and they have threatened to delete Book Chase in 20 days!
