I'm 59 years old (which I'd guess is way over average in this community), an atheist (my parents were atheists but took us to a local church for a while, perhaps just to expose us to what's out there), avid reader, parent, husband, and programmer for over 30 years.
I heard about OB when it started, from several other blogs. I read OB and LW fairly often, but not exhaustively--there's never enough time.
I am skeptical of some conventional wisdom but also of alternatives. I didn't like collapsing wave functions when I took QM and also didn't like many worlds when introduced by a physics-major friend. (I doubt if I'll dig into QM again--my brain has lost some of its edge.)
