+1 I stop sharing my opinion with my network because of this same problem (I have clients, close relatives, extended family, etc.). What if I post something that a client finds offensive and leads to business problems that otherwise wouldn't have existed? What if I post something serious for my clients and some jackass high-school friend leaves an embarrassing comment on my status? Initially, I had to block the ability for people to tag me in photos because I was being used to spam other people's walls, then I had to block other people from posting on my wall, because they would post "funny" stuff that wasn't good for my business-contacts to see. Finally, I started using lists, but having different "personas" for each list was just too much. As a result, I'm slowly letting my profile fade away.
