Facebook's next decade: 4 things the network should do

[Commentary] What Facebook must do to stay on top in the next decade.

1. Focus on mobile -- The future for Facebook will be primarily about mobile, says Jeremy Liew, a partner with Lightspeed Venture Partners and investor in Snapchat and Whisper.
2. Diversify -- Facebook could consider expanding into e-commerce by providing back-end services for businesses, or selling goods, whether physical or digital, says Brian Blau, research director in consumer technologies for Gartner, a technology research firm.
3. Satisfy marketers -- With its vast reach and specialized data on people's preferences, Facebook has the potential to redefine how companies target and market to customers on the Web. That hasn't happened yet.
4. Privacy concerns -- The demands of satisfying both marketers and users may be at odds with each other. "Because of Facebook's business model, people share information with their friends and Facebook then makes that information available to advertisers. But that's a problem form a privacy perspective," said Marc Rotenberg, executive director of the Electronic Privacy Information Center.
