I’m very impressed with the About.me iOS App! (the iOS 7 version to be precise!)
They took a boring and crowded niche (digital name plates) and made them fun again!
I do like the business/social aspect of the app as it helps you to find interesting people minus the “biz spam” (which is why I stopped using LinkedIn).
Oddly though the About.me app is a little slow on the response side (especially tapping on people’s profiles) but aside from that I really love the UI.
Note: Sadly there is no About.me app upon Google Play, which means my Android brethren and sistren are (once again) abandoned to the cold (something Windows Phone cultists are use too).
