And somehow, Twitter, Groupon, Instagram etc., have not yet figured out how to actually make money off of those 2 BILLION PEOPLE. And last time I checked, making money was the whole point of investing.

Edit: Just to clarify the above, making money == making a profit. I think that's pretty well understood in business, guys. If I bought a single share of stock for $100, and sold it for $50, I sure as hell did not "make money" on the deal, even though I gained $50 in revenue from selling the stock.
