Sure but I doubt it. For example after initial students on college campuses who started using Facebook, it has spread to older generations and people in 30s, 40s even 50s now use Facebook. With Snapchat I don't see such trend. It has no website, only a confusing mobile app with horrid UX that most people can't figure out and is mostly used for adding pig noses and cat ears to pictures by teenagers.
