at this point in time: nothing that I can think of. I know that some people swear by the power of social media but to me it has become an unwelcome source of ever more e-mails in my inbox.
From what I can tell: people will find me if they really want to. I also deal with predominantly older adults and non-facebook users, so to me that whole facebook thing is rather irrelevant.
I guess that is an answer for your ‘negative’ column.
