I use it a bit, look in a few times a week. You can search for and read about books. There are discussion groups
but I don't know how many people spend the time to really read through the discussions. Like on Facebook,
I'm always wondering if people just contribute their bit but don't read what anyone else said. Hmmm, sort of
like real life when no one's really listening... Anyway, It's interesting to see what other people think about books
I've read and a few people have commented on some things I've said. As far as publicity, my publisher has Goodreads
discussions and it might do some good.
