The timelines here are pretty long. Facebook has been around for 18 years, Twitter for 16. That's more than a "fad". These companies are lasting as long or longer than other tech companies, certainly longer than your average start-up.

Except that Facebook is nearly irrelevant these days. Facebook is relevant only because of its acquisitions of apps like Instagram, WhatsApp, Oculus, etc. Twitter doesn't have that.

They all fall! It used to be quicker, but they all do. It's clear Facebook is fading. And it's a separate issue from anything "wrong" the platform does. The userbase simply ages, and kids don't want to be where their parents are. I have a facebook account that I only use for high school reuinons. My classmates post photos of their grandchildren, etc.

Although I generally agree that most social media platforms are fads. I am not sure about Twitter. At least I know that it will stay around for a long time. It did so despite all it's problems so far.
