I've lurked here a long time. There are younger people coming in. And most of them are used to the wider 10' 20' internet culture they grew up on. So you'll see spamming of stickers from people thinking its a downvote button, as if a post will be rendered invisible. But never actually interact with a post to provide an argument or deconstruction.
When posting in a thread, act like it's Twitter or Reddit. To provide what they think is simply the best "hot take". Most of these newer people never provide content at all. In fact, despite being on the internet, on KF, they will ask for a link or source. When it's obvious all you have to do is type the term into the search bar and what they asked for will appear.
