One peeve I have about businesses that get themselves a social media presence is that they often do something like this:
Well. Okay. So you want me to follow you on Twitter and Facebook. If so, why don’t you tell me how I can do that? If I don’t have your Twitter handle or Facebook URL, how do you expect me to come by?
Not posting a twitter handle or Facebook page URL is the online equivalent of inviting someone home but refusing to give them your address.
