>I saw some usage data in a quartz article, that I can’t find, earlier this week. Facebook was the most popular social media platform across teenagers, millennials, generation x and baby boomers.

It's really surprising to me. I don't see anyone around me using Facebook (or only to meme on large private groups). Messenger is still prevalent but more for legacy reasons than anything else and can be displaced. It reminds me of MSN messenger. Wizzz!
