Cramer Answers Twitter Questions on Coke, Gilead, Yelp and Radian

Jim Cramer answers viewers' Twitter questions from the floor of the New York Stock Exchange. This week, Cramer reveals he's more of a fan of PepsiCo and its snack and beverage business than Coca-Cola. He also weighs in on Yelp after what he says was a good quarter but one with a popular view that it wasn't quite good enough. Cramer says there's a slowdown happening at Yelp that the company doesn't want to seem to admit. Facebook, however, is the opposite of Yelp, according to Cramer. He calls Facebook's most recent results a 'beautiful quarter' and says investors should pick their spots to buy. Plus, Cramer reveals why he's changed his stance on Twitter chief executive Dick Costolo, someone he has said in the past should not be at the company's helm.
