40 year old, here. I mainly use snap to play with filters with my young kids. I'd never use it for communication because the UX is horrendous. A while ago, there was an odd corporate push to try to use snap internally (was there some marketing push?). And, all of my co-workers spent lots of time brainstorming how to even use snap effectively.

The swarms of 13 years olds that roam through my house only ever seem to use their mobile for Instagram, snap, and youtube. However, more recently I've noticed that the boys have been walking around with bluetooth headsets on as they have a large group chat going on in the background. Not sure what app they're using.
