Buried at MSU is H-Net, a great resource for book reviews and posting/contacting scholars in the humanities and social sciences. What is great is that it is home grown and shows the potential for cooperation and new types of jobs for the 21st century.
The skinny is that there are numerous discussion networks that you can subscribe to and read discussion threads, book reviews and post questions. Citation checking to where can I stay in DC for cheap for a conference. For librarians and others wanting more detailed book reviews, the review tab is the place to start your search. Scan the the discussion lists, there is probably something there for everybody to enjoy.
