I always look up all my doctors on facebook at the very least to see if there is something that should concern me. If I can't find them in facebook they either technological challenged (which to me might mean they are not up to date on the latest treatment since the medical field has become so technological dependent) or they are paranoid of being found by their patients/feel a sense of superiority. In both cases it is a major turn off. I never contact them on facebook. As a matter of fact I even blocked my current T on Facebook so he won't see any comments that I write in a public forum.
