I thought the same until I picked it up again a few months ago. There are several factors to it's success (IMO) that are immediately obvious to my demographic (20-30): * It's simple, stream-lined, and private (to an average user, maybe not the HN crowd) when compared to Facebook or any other social app. * It appeals strongly to both men and women, which I think is an underrated aspect when it comes to viral tech popularity. * It can be a more modest form of flirting then Tinder, or a more personable touch then text messaging, often playing a role in relationship building of all kinds. * It's fun and free. * It's a fantastic way to keep in touch with old friends, being much easier then a phone call (to the socially anxious among us) and providing a visual connection showing exactly what you are doing in that moment.
