Yes, there is a Facebook group for this blog. It's true. And you can join the "A Blog Without a Bicycle" group on Facebook if you enjoy social networking of the profile-based kind.
Please note that as my M.A. thesis project is complete, the George Washington University is no longer overseeing research conducted in conjuction with this blog (effective June 2007 to present). The Informed Consent Materials created while this blog was under GWU's IRB oversight are still available for your information and the principles outlined in them are still being used as a general guide for my continued work.
