Privacy concerns with social networking sites
I recently noticed that a former co-worker had disappeared from LinkedIn. When I asked him about this he explained that he had canceled all of his memberships in social networking sites because they were asking for too much personal information and didn't seem to take his concerns about privacy seriously. He then went to to say, "I will not be pushed, filed, stamped, indexed, briefed, debriefed or numbered. My life is my own. I resign."
I did warn him that things didn't work out too well for the person who said that the first time, but he didn't seem concerned. All I could think to say was, "Be seeing you."
