I recently made friends with a like-minded individual that has very similar tastes to my own on ebooks. I would like to be able to "follow" or be "informed" when he or somone I like posts a book or file.

I know many of us don't have the time to spend wading through thousands of pages of ebooks/files to find the ones we like and the books are "mostly" sorted by catagory so would it be possible to be "notified" if a book on a certain topic or uploaded by anyone on a "list" is posted?

Perhaps a "virtual card-catalogue" could be made by the people posting answering two or three questions about the book/file they are sharing?

just some ideas
