I agree. There's a separate panel here, started by Trey Ratcliff, about Google+ that got me to see the magic here. I am also dreaming of a world of augmented reality and think this will be an important community to build and place to have conversations as we head toward that, too. I am watching Reddit, YouTube, and other spaces, which are very interesting, but I sure see so much corrosive behavior in those spaces. It's to the place where it's not fun for me and I'm not usually the one getting the brunt of the bad behavior.
