I'm reminded of something CharTec CEO Alex Rogers said when I visited the CharTec Academy: There's nothing a savvy MSP shouldn't offer their customers. Rogers even said he'd mow his clients' lawn if it came to it. I can't see any reason why service providers, cloud or otherwise, shouldn't use Facebook for Business to promote local presence and community management services to local customers.
In fact, I can't help but suspect that Rogers would see it as a foot-in-the-door scenario. Small business customers may have no idea what "cloud storage" is, but odds are pretty good they know about Facebook if they don't use it already. And Facebook for Business could be the perfect way to introduce the idea of monetizing the concept. If you're already providing web site design, add on the Facebook page listing for free, respond to comments once a day, and the customer is yours forever.
Google+, Google's own social network, has been making headlines and garnering chatter. But it's not opening up to enterprises yet, and business profiles are only starting a field test within the next week or two. There's no reason why service providers can't ride the social networking wave, one way or another.
