VIDEO: Zuckerberg Talks Facebook's Future, Mistakes, IPO at TechCrunch Disrupt SF

Facebook's CEO talked about the company's future, a possible search engine, its "disappointing" IPO and more at TechCrunch Disrupt SF on Tuesday.

Facebook is going to focus more on mobile going forward, according to the latest story on .

TechCrunch backs that up with this story on Facebook's mobile future: "We are going to make a lot more money than on desktop," Zuckerberg said. Those mobile users also are the ones Zuckerberg says will return to the site day after day.

Wondering why the Facebook app on your phone was ridiculously slow until, oh, last week? Zuckerberg talks about that too, and why it won't happen anymore—also on TechCrunch.

Huffington Post looks at the tough questions Zuckerberg faces, after Facebook's stock performed lower than expected. TechCrunch also has its take to Zuckerberg's comments on the stock price.

But Facebook still is a great place to work, Zuckerberg said. The company also will build likely a search engine; continue to break and fix things; and keep an eye on other successful start-ups.

Finally, Zuckerberg said on TechCrunch that he would rather be underestimated. On that note, Facebook's stock rose 4.6 percent in after-hours trading following his speech.
