I recently went on Instagram for a week or two and it looks like it's all business accounts that get the attention and do the posting, private people's accounts are mostly not public to begin with. I see people haven't posted to their account since 2018 but are active daily. Photos are no longer shared but videos, even single frame videos which could be a picture are now uploaded as videos.

I think largely the same. Seems like a personal journal / art project and a lot of people keep up with each other using constant content as a medium. Not my cup of tea, but I know enough healthy cool people that participate for me to believe it can’t all be bad. A lot of them even keep their account private so literally doing it for their friend network only.
