As someone who doesn't use FB I wouldn't be switching, but I will probably give it a try if after a week or so I don't hear anything insane from the early adopters. Unlike FB I have some faith in google not intentionally screwing their user base.
Probably wouldn't switch, unless it was a REALLY killer app.
The userbase is SO dedicated to Facebook, this is a LONG road for them to go. I can't think of anything else they've done (other than GMail) where they've moved a BIG userbase away from things they were already REALLY accustomed to. GMail did so because it was RADICALLY better than any of the alternatives at the time. What can really be RADICALLY better at what it does than facebook?
I shut down my Facebook account because of the psychotic way they handle user privacy. I'll definitely give Google a shot and might keep using them if they promise to not be evil.
shit, I deleted my facebook account because I became addicted to stalking almost everybody I know... with google me, it's going to be tougher to delete it..
I sure hope Google will release something unique rather than another social network site.
