I'm 36 and using it a few times a week, mostly with my much younger siblings in their early 20's. Another family friend who has a daughter got her first smartphone recently, and snapchat was one of the first installs on that device. I used it as well pretty heavily when it first came out to keep in touch with family and friends.

Weirdly enough I have an interview with Snap in a few weeks as well. Despite the drop that tech stocks have seen everywhere the last year or so I think it's still a strong company to try and join.
