Looking for a great collection of book-related blogs? If so, be sure to check out the book section of the Alltop aggregator. The approach is similar to what Original Signal features, but Original Signal doesn't offer a book-focused page. I love it that the 5 most recent posts from so many book blogs are available to me on one page; hover your mouse over any of the headlines and you get to read the lead-in paragraph. All this without having to navigate back and forth through an RSS reader. It's a great alternative and an excellent way to quickly catch a glimpse of all the headlines.
I was glad to see that Alltop discovered my blogs before I discovered them. You'll find both Publishing 2020 and Kindleville are already included in their lineup. Send them an email if there are other blogs you'd like to see them add to this service.
