The Zeitgeist of the internet of the 20s is considerably less kind to people who form their own thoughts.

This rings true and it may come from the wider world. Seems to me that we have entered an era of fear and pessimism. Partly as a result of that, today's younger generation had protected childhoods and now, given the state of the world, they themselves are afraid for their futures (with some justification). All this is creating an atmosphere of hypersensitivity, aversion to causing offense, a general lack of openness to new ideas and contradiction.

Nothing I say there is particularly original and I can't offer data to support it. But my anecdotal experience on this forum and elsewhere backs up the hypothesis completely. Something has changed.

I used to use Reddit some, although I would never manage to stick with it well and become an accepted regular anywhere, but it was big enough that I never realized it was a link aggregator before all else, since people were just talking about whatever in communities. I actually had to look up some fediverse site yesterday when checking what’s out there for blogging and whatnot for it to label reddit and lemmy explicitly as link aggregators, for me to really get it.

Forming their own thoughts, is it the voting, is it the culture wars? I know I have the chilling effect of thinking that my response to some article will just get tons of downvotes so why bother. And I don’t think upvotes mean the same thing to me that they mean to the average person.

Coordinating with other people, I’ve had zero success with and must just not have any clue how to go about it.
