I was not a fan until recently, but my wife and her friends have been avid users for quite some time. A. Frictionless sign up. easy to find friends [1] B. Extremely efficient to 'share' photos with the world, i.e. Facebook, Twtter, tumblr... C. Photos look good. Like, exceptionally good for just snapping your dog outside or some random place. If you use Instagram (or other filtered photo apps) you start to realize 90% of non-professional picture taken without filters look like crap. D. It is a photo sharing network. Except the photos are good. Its mobile-centric. And fairly effortless. 1. Something about finding "real" friends and starting a "new" network is very refreshing (i.e. Path's thesis). Get rid of the hundreds of FB posts I don't want to see, now just see a niche group of friends photos (not /rants) & make my photos look a lot better than 3 seconds ago when I took it.
