Wossy Book Club is clever down to its core. The forum functionaility itself was taken from bbPress, the open source forum software from the creators of world-leading blogging software WordPress. The idea of the book club is that it runs through Twitter – it’s a Twitter book club after all. To integrate the two web sites Twitter OAuth has been put in to the core, with user registration and logon powered through the Twitter API. If you haven’t already joined, then sign up through Twitter now!
