Businesses enter the social media world to benefit their company. @AskAmex, American Express' Twitter Team, was created as a customer service tool to deal with questions and complaints in an efficient and cheap manner. And in Boeing's case, they got the chance to provide a measly explanation of their cold-hearted behavior in response to Mr. Winsor's concern.
But the risk of allowing employees to control the social media of big corporations seems to outweigh any benefits. What it all comes down to: trust. Will employees intentionally or unintentionally ruin the company's reputation? Will they lose control of content being posted? Will the use of business social media lead to the use of personal social media on the job, creating a lack of productivity?
Companies used to completely ignore the social media existence by blocking them in the work environment. But now the time has come where they have to embrace the new communication technology or get left behind. In response to the risks addressed, companies need to develop risk management. They need to assign one person to the social media project. They need to learn how to control what can be said by employees, as well as visitors to the site. As for the possible lack of productivity, it's been suggested to hold training sessions on order to educate employees on social media. It's a nice thought, but will it work? Doubtful.
