Anywhere we can post to find people with similar interests?

For example, I'd like to find fantasy book fans, specifically ASOIAF and Malazan if possible. So far, I don't see a books community where I can ask this, and entertainment doesn't appear to cover books from the looks of it. I don't really want to post the question here, but keen to see if anyone else is into these series and not sure where else to post!
