This review aggregation site does what it says. It compiles reviews of products for you to look through. Right now many of them come from Amazon, typepad, and other blogs I can see bigger things happening here. It's fast. You can snatch reviews for music, movies, books, etc. Check out my review of Tia McCollor's Heart of Devotion.
The section I think is most interesting is the Trends section. You can see what books are getting the most talk and join in the conversation. As soon as I have time I can't wait to chime in there.
Have anyone used Summize? Are there other better review ajax like applications out there?
