Andrew Keen of Telegraph.co.uk writes today that if giants Google and Microsoft want to succeed in social media, they must take a few things into consideration. For instance, Keen would like the giants to read Trust Agents. "The companies that will win in the social media economy are those who figure out how to both create and profit from trust," Keen says. Also, its important to remember that we are still in the "early stages" for social media; however, Keen contends that "we have yet to see the great social media company that will radically transform the world. And I suspect that this company’s secret-sauce will be based upon the agency of trust."

So what do you think? What can Google and Microsoft learn from Facebook and Twitter as they attempt to enter the social media sphere?
