Seems pretty hyperbolic. I joined through my insta out of curiosity and I saw like half my friends posting stuff already, saying hi or an update about their life. And all the meme accounts I follow were already posting shit ofc. I'm sure a significant fraction of Lemmy's interactions are based around meme posts, so we're doing the same thing they are. That's just how humans like existing on the internet.

For the record I'm anti Facebook, but you can't get around the fact that almost all your friends and everyone you see walking around likely has an Instagram account. It's just a given and I feel like people here hate acknowledging that.
