Well, the subject of this topic is the original Facebook itself, not its other properties like Instagram.

That said, if I'm not mistaken I think Instagram too is deemed to be something for "old" folks by the current set of teens, tweens, and younger twentysomethings.

“The platform got better when children started using it” said no user ever.

The fortysomethings I know also think it's only for old folks. Do thirtysomething's still use Facebook ironically, or something?

Not among my peers. Facebook is seen as a way to communicate with older and tech-challenged relatives. It's in the same category as LinkedIn -- a social network whose content is mostly cringe and that you're only on as a means to an end, not because it's a good product.

I was ridiculed in my local cafe for not having a Facebook account. This was by people in my age group (mid fifties).

I had an account years ago but abandoned it as soon as they started to monetise (same for Twitter).
