So if I actually had a Pinterest account, would I see something other than makeup tips and pictures of cute babies?
Excellent article on how Pinterest's boards are much better than Google+'s circles, which, as I've said before, totally miss the point of sharing. Money quote: "Both the pinner and the follower only have to think about their own tastes. They don't have to guess what other people are like."
Possibly. It's mostly crafts, and they have a categorization problem, but there's some pretty interesting stuff in there. Point being that they do segmented sharing in a more logical way than Google+: letting people decide what they're interested in rather than having you decide for them.
It does sound like a good idea. I don't know if you've seen it, but there's an ad for some Android phone that shows people frantically running into circles (i.e. Circles) while the voiceover talks about what a great system it is. I can't think of a better way to show Circles as unnatural and inconvenient.
TOTALLY. That ad makes me crazy. "So you can organize the people you know into circles, like you do in real life." You're so right: seeing it played out like that with actual people shows how wrong-headed it is.
