I de activated my FB few years ago. I have no friends and nobody likes me, anyway. But, I almost immediately realized after deactivating that several things I like either required or were, unbeknownst to me, connected to my account. So I made up a name, gave him an address and birthday and all that, and now I can play poker and candy crush, listen to pandora, etc without giving my personal information to a company I do not trust. I have just never really understood why everyone thinks everyone else gives a shit what they are doing today, or who they are with, etc. Twitter is equally baffling to me except as a marketing tool. And wtf is LinkedIn, really? Why do people I have never met endorse my skills in areas I will never share with them?
