An example that probably everyone can understand is youtube. Content creators are often begging for like/subscribe and even present graphs that show that only 10% of their regular viewers are subscribed. This seems like a social problem to some, but in reality it’s a technical problem because if you like/subscribe, your feed will drown in “similar” videos of much lower quality and that will haunt you for weeks. And there’s a whole set of other ui/ux issues even if you decide to subscribe. So many people avoid interacting with videos too much because of that.
I know youtube is a beaten horse, but it is a textbook example of what I mean. I could theorize about what’s wrong with wikis, but wiki guys see it much better. My key thought here is “check twice that it’s not technical before calling it social”, but it may not be the case here.
MediaWiki uses the term "category" for its system of tagging pages. This generally is used as a very complex system of hierarchy with many nested levels and prescribed "correct" categories.
Some people think we should use "tags" instead (e.g. less nesting and more intersecting. Instead of a category "People in Belgium" use a tag "People" and a tag "Belgium" and apply both).
On a technical level the feature requirements are basically the same, but the word tag and the word category have such strong connotations that the mere name strongly supports one social organization over another (imo)
We definitely need an official Discord equivalent with wider adoption. I can't effectively use IRC on my phone and computer simultaneously. In terms of editor outreach, I don't have any easy answers. Wiki Education is very good at bringing in editors.
The amount of trivial self-defeating ideas that for some unclear reason supposed to prove the absense of a solution - with the current solution being a dead stupid counter - is amazing.
