Be careful. Do not create a Facebook, Twitter, LinkedIn, or other voluntary social media business page unless you have got the time and personality to create content in a timely manner. Twitter users expect at least a same-day response, desirably faster. Facebook users that have been kind enough to "like" your business expect helpful postings at least weekly. You might be able to keep them involved and propagating your postings if the posts are truly helpful, substantial, and at least monthly. Anything less frequent will lead them to assume that your business is not doing well and/or that you don't really have the time to bother with them. Even worse, new potential customers will likewise conclude that your business is not doing well.
Things can get even worse with reviews on the myriad local search engines. Sometimes no response is best if you have the personality that is inclined to argue or become offended. However, if you have the personality that allows some consideration to be offered, a timely response is even better. Timeliness is the key, e.g., responding weeks later unfortunately implies more about your indifference than anything you could write in a response.
