I've been wondering about G+ but I don't really know anyone that uses it. I guess it would help if I actually took the time to check it out for myself . . .
They've set it up so you don't have to. They've got communities that function as better subreddits, then architecture similar to hubski with tags and circles (although it would be great to have something like a badge), most people are using real names and photos so it's got a more intimate feel, but the privacy controls aren't built to emphasize voyeurism (looking at you facebook), so it feels safe enough to minimize posturing (looking at your again facebook). They've got hangouts built in so you can live cast or conference really easily. And everybody seems eager to interact and circle ya back. Plus (lol), the more you use it, the better the whole google platform gets for you. Worth a shot I'm telling ya.
