Few months back I got jealous and installed Snapschat myself. It conveniently scanned my contacts, and found that none of my friends are on it. (I’m late 30s.) To this day, the only snap I received is the default welcome message they send to everyone.
They’re doing a good job of confining their appeal to their target age group. The minute I and my peers appear on Snapchat, it's time to get worried.
And then there's snapchat.com, which is another enigma. I consider myself a reasonably competent technologist but Snapchat makes me feel like an ape trying to figure out a mysterious monolith.
