True, but unless you place some really strict filters on the crowd you're sourcing from, odds are the vast majority of it will be bad, and make you dumber.

'Tis the reason why I stopped using any sort of aggregator (Slashdot, reddit, Digg, etc.) for any news. The average intelligence and professionalism demonstrated on such sites is so low that I'd rather be staring at a wall than reading those sites.

More generally: Bad journalism makes you dumber. Good journalism makes you smarter and saves you time.
