Handheld two-way radios, apparently

So IT guys are antennas.

A wiki is probably what you want. I was going to suggest tvtropes, which is great for, say, a list of every superhero with X-ray vision, or every work of fiction containing dwarves, but I’m not sure that fits what you want.

I just checked this out. It’s not quite what I’m looking for right now but it does answer my question as asked. I can see it coming in handy later.

I’m getting two points from the article. One is addressed handily by the Fediverse, the other is not.

First the centralized (I prefer to say “urbanized”) nature of social media means a handful of companies control all the conversations. The Fediverse is a decent (though not perfect) solution to that problem, and I think everyone on here knows that.

However, the article also talks about the problems with the format of social media, not just who’s hosting the platform. On traditional forums, conversations can last for years, but on Reddit, Discord, etc. new topics quickly bury old ones, no matter how lively those old topics are. Sure, you can choose to sort by “last comment” which replicates the traditional forum presentation with topic bumping, but it’s not the default, even on Lemmy, so 90% of people won’t bother.

I get to know people on traditional forums, even miss them if they leave, but on Reddit, comments are just disembodied thoughts manifesting in the ether. That may be due to the size of the community rather than the format, though.
