Blogging unpublished books

I watched the clip about Lou Rosenfied. He makes a lot of valid points about publishing that I could relate to considering I'm work at Borders. I'm surprised it is so hard to be published at that so many authors are going independent. I applaud his attempts at advertising books. I had never realized blogging could be a convenient advertising tool for a book of all things. I assumed the regular forms were just commercials and reviews in magazines. The blogs help give feedback before the book comes out, which I believe will help gives the audience a book they want before its out and can be criticized later. I think this is definjitely a positive new wave for literature.
