>I apologize in advance for sounding like an elitist prick, but in my mind, community-driven sites like StackOverflow, Reddit, Wikipedia, are prone to the noise of do-nothing armchair experts (especially in this economy with the unemployment rate) who have nothing better to do than stir philosophical debates over nothing.

One man's "philosophical debate over nothing" is another man's passion.

And one man's "productivity" is another man's who gives a fuck.
