[doktrin]

The challenge was not directed at me, but I'll take a brief stab at it :

"It is morally acceptable for some of the brighter minds of a generation to invest their time, effort and energy into developing social products - including but not limited to Facebook. These are fully legitimate free market business ventures, and we need to stop collectively pontificating about what may or may not constitute a socially worthy business goal."

This is, I believe, a more concise summary of the parent's perspective. It meets a different need, and I don't view it as being "better" per se.
