Blog Demographics uses 3rd-party-services (Facebook, MyBlogLog and BlogCatalog) to access the identity of your viewers and commentators. 
In order to work at all, you need at least one account at such a service.
Blog Demographics retrieves a list of recent visitors from those accounts. If the visitor didn’t specify an age or gender Blog Demographics tries to access associated accounts like Facebook or YouTube to get those informations. Facebook is also used to retrieve gender and age of your commentators.
