I absolutely support anything that makes reading more of a social event. I have a hard time getting friends to read books that I like, so I am really liking the direction that eReaders are going. I know, this may handicap the conversation as some are completely opposed to ebooks. Personally, I like books, but love to be able to carry around my whole library on one device.
Anyway, I think this is actually a pretty good idea:
I know it can never replace book clubs, etc., but it could enhance them. I proudly support Kobo and open format epub books.
