Glassboard is a private social network, something that a lot of people find an incredibly attractive to the very public, and often privacy-challenged Facebook, Google+, and like networks of the world. And it's just re-launched with an all new, all-iOS 7 update. I've used Glassboard for conferences for years, and been beta testing Glassboard 3.0 for a few weeks now. It's a great app, and it's great to see it getting so much love. (The snazzy new icon by Marc Edwards doesn't hurt either!).
