I have closed my LinkedIn account, since I have no need to connect with the people instrumental to my previous work. It was just giving me unsolicited offers. Now I am weighing the benefits of Facebook. I thought I would post who I was, but what I need to post is what everyone else wants me to be. It is another opportunity for malware, and a huge inconvenience every time someone tries to check into my account. (I have their IP address and their street address). What good is it?
