leading this company, would you tell your friends to buy facebook stock? >> if i could predict the stock market, i wouldn't have to have a job anymore. >> but i mean, are they doing enough to fix this? are are they doithey doing whato be doing? >> here is the challenge. i understand someone like mark zuckerberg having so much power. no one elected him into this position. but the ultimate version of public information available to public company is responsible to wall street. facebook needs to focus on growing more slowly, being careful about moving into new markets about what kind of impact that has, skpin veand ina lot of money into safety and security. they seem to be doing that. that's going to cost a lot of money and make the stock go down. there is a difficult part here. if you want the company to be responsible to the shareholders, that's probably actually going to hurt instabilithe ability toe problems in the long term.
