I am one of the moderators for the Book Blogger Directory. If you haven't checked this out yet, you must get over there ASAP! It's a place for book bloggers of all genres to link to their blogs. There are a lot of YAogs and also a lot of Adult Fiction blogs, plus blogs featuring other genres.
The BBD also has a Blog. One of my main goals for the Directory is to feature and help promote new blogs. I'm starting a series of interviews with blogs that started within the past several months. If you'd like to be featured, shoot me an e-mail.
