I haven’t had the chance to play with Google Buzz yet. I’m usually an ultra-early-adopter, but I’ve been too swamped with work these last few days to do so.
But frankly, after reading the panicked privacy reactions from early adopters, I’m pretty glad I didn’t.
Email address publishing? Autofollowing? “Terrifyingly accurate” Android location awareness publishing and posting photos from cellphones that were never before uploaded?
And everything’s opt-out?
It’s like Google carefully studied every complaint, real or imagined, about the privacy practices of Facebook, Twitter, etc…and then rolled all the rollicking horrors into one service.
edit: Grimmelmann agrees.
