Like lots of things, is it the "whole truth"? Can any real conclusions be drawn?
Similar things can be send about twitter.. texting... use of cell-phones in general... I suspect that folks had similar reactions when telephones came out, then radio, then television.
I'd like to see a study of all the folks that do studies to see what the studies themselves cause... No one, or very few, seem to want to examine our unquenchable habit of studying everything.
