From my anecdotal experience, of what my close friends share with me via DM these days, sadly it is indeed 95% video, and it is indeed 95% Instagram / TikTok / Facebook / Twitter / YouTube (in descending order). I continue to share with them 75% long-form articles, and 75% personal web sites / mainstream media web sites.
I actually looked a bit yesterday, and checked FB particularly to see what the situation was, and maybe have my own anecdotal take.
At least part of what I found was that there did not seem to be much actual discussion. It didn't really even matter whether it was a video, a text article (like making food), or an event. A huge percentage of "conversations" ended up being nothing more than notification references after the first 20-50 comments. It was really rather surreal to look at. I hadn't logged on in a while.
Initially, I couldn't even tell what was going on. Comment after comment where people just stated someone's name and then someone replied with someone else's name. In most cases, once the back-and-forth name reffing started, all actual conversation died quickly.
It's technically "sharing", since they're notifying FB members of being mentioned somewhere. Yet it doesn't really go anywhere externally, and very quickly kills off all further discussion in thread.
Yes, I see that all the time on Facebook too, top-most 10% of a thread is actual comments, bottom-most 90% is "Friend McFriendface" name reffing. It's quite annoying.
