Been playing with Goggle+. So far, so good.
I like “circles”, which are groups of people who see this or that post. When you post something on G+ you can select what circles are allowed to see it. Something nerdy? Use the “geek” circle. Pix of your backyard? Pick “family” and “friends”. You start out with some default circles but you can create your own. You can place people into multiple circles as well, which is very handy.
Circles also let you filter what content you’re seeing from the people you follow (or “friend” or “plus” or whatever). Also very nice.
More broadly I feel less uncomfortable with Google than I do with Facebook. I’ve closed down most of my Facebook accounts; I have zero trust in Mark Zuckerberg and see Facebook now as a (currently) needed marketing venue for some commercial ventures but not for anything personal.
Google+ seems to have a better take on privacy, and hopefully people will be holding Google accountable from the get-go on this, as opposed to the Facebook bait-and-switch after lulling users in.
