Reading through his list of topics, it seems he's had some "debates" with Ernest W. Adams before. A bit surprised to see Ernest there, as he usually pops up on Facebook, and it got me wondering if he's a member here too.
Anyway, I'd be interested to read more, but I have to ask, is Quora worth signing up for? It looks like yet another Q & A site, but possibly lower quality than Stack Overflow / Stack Exchange (if a bit wider in topic range).
