i love using discord servers as a knowledge base!!! i love having to figure out which channel to check the pinned messages in and then scroll 15 messages down before i can find the very basic information i'm looking for!!!! this is such a great system!!!!!
It was wikis. Wikis were - and indeed, if you can find non-Fandom wikis, still are - probably the best way to store and share information like that. (I mean from a non technical user standpoint - just in terms of how easy it was to find the information I was looking for and, if I couldn't find it there, easy to update with the information once I found it elsewhere.)
I know part of why we stopped was so many wikis got gutted by Fandom and similar commercialization efforts ruining them, and so many of the discord servers are because it's easy to do mindlessly but like it was so much better and I just miss the day where everything had a usable wiki.
