My answer to Is social networking good for businesses? Why?
Answer by Ken Larson:
Personal, professional and business branding is occurring regularly, whether or not we are aware of it.
From our web site presence to our postings on the sites of others, from our credit ratings to our cell phone records and application navigation, we are tracking others and being tracked ourselves.
Deciding to become active in social networking is really a matter of managing personal, professional and business images/brands or having them manage us.
