I think the unfortunate reality is probably more than 80% and this is a conservative number are just here to make money or some people may say as "extract". If making money wasn't involved, then we would probably see the "REAL" people that were actually here to write, build and be part of something. If I'm not wrong, X is also having these issues as well where people are just faking their impressions and views with their "content" to get paid.

As for valuable engagement, that can vary depending on person and post. Posts like the one I'm commenting now are more opinionated and controversial may spark more lengthy discussions. Then some topics more people are passionate about like gaming etc then they can add more input.

Anyways personally for me, I feel valuable engagement is where the person was genuinely trying to comment first of all and it doesn't matter the length of their comment but you can see in their comment that they did read what was posted and tried to add some sort of input or opinion. Sometimes even a simple thanks for the info if they learned something new is good enough. It really depends on what was the goal of the post and I don't think there's a perfect answer for valuable engagement. everyone will have their own take on it~

we are now in a fast paced world (we want everything fast and this includes making money fast) where ai can summarize stuff for us and our attention is now stuck to short videos of 30 seconds to 1 minutes maybe even less. The brainrot is real and I don't want to go down the rabbit hole but I'm pretty sure it was all a plan to poison the minds so people can't think and truly see what's happening around
