For those who would like even more nook (& book) friends than the BN book clubs provide, there's also librarything.com That site has lots of interesting features on it. For example, once you enter the books you own (or have read), the site will show you who else has a library with many of the same books. You can friend those people or just follow them to see what else they read. And it has an "unsuggester" ("if you like this book, you probably WON'T like . . .") And it has free book giveaways (including ebooks) for people who promise to write a 25-word review of them. And lots of other features I can't list here. I like it, anyway.
