According to Statista, as of Fall of 2018, the two most used social media platforms by teens and young adults are Instagram and Snapchat.
Correct....My ignorance of SC fairly explained by my own age of 58.
But overall social media is still driven by Twitter, especially among the journalists, legal professionals and of course those in the political fields.
Those outside the aforementioned demographic (age 18-50) may well roll their eyes and decry these platforms as "young loudmouths making the most noise", but in doing so they reveal the ironic paradigm shift - that is, the primary lines of social communication in the year 2018 and forward will be driven by people aged 18-50.
And five years from now, it will be driven by people aged 18-55.
Anyone older than that might sneer at this reality but ruefully, increasingly less people are paying them (those older than 55) much attention.
*I* am just happy that I've managed to retain a fair number of connections w those in the younger demos...My three adult kids in their 30s, my five business partners aged 28-45 etc.
Otherwise I myself might be yelling at the majority of Americans younger than me and being frustrated that they refuse to listen to my telling them "how things worked back in my day!!"
