Here's an interesting bit of info from Publisher's Weekly:
Newspapers may be continuing to cut their book coverage, but the Internet is home to an ever-expanding hive of blogs about books. Some 250 book bloggers attended the first-ever Book Blogger Convention in May, an event held at Manhattan's Javits Center the day after BEA ended. Sponsorships from major New York houses and lots of love from independent presses helped cement book bloggers' place in the industry. Here's a list of all 200-plus attendees and the links to their blogs: bookbloggerconvention.com/attendees.
If you click on that "attendees" hot link, stand back. A horde of blogs will come pouring out -- some look interesting. Of course, there's always room for one more, if you decide to create your own.
