At the cost of proving my technological Amishness, allow me state that Google+1 leaves me cold. Perhaps, I don't understand its utility, or maybe my willingness to share is low, but my concept of a social network involves physical people, conversing, sharing, not tethered to an electronic leash. Suddenly, and I blame +1, formerly warm, cuddly Google now feels like an early incarnation of Darth Vader.
I'll grant, it is new to most of us and I am willing to learn. To maintain my multi-universe citizenship papers I have signed up for a Google +1 account, then instantly threshed my crop circles, dammed my streams, locked down my Picassa photo albums, signed out of what services I could and pulled up the draw bridge.
I too often rely on your good graces to protect me from myself, and friends this may be one of those times. I'm not "worried" yet about whatever privacy issues may be spun from this demon, but until I understand its "why this is good for me", I'm not going to play +1. I do have an openable mind however, and if someone has a REALLY good reason to play, open up, I'm all ears. You may change my world.
