Besides the whole Fediverse, what are some underrated places on the internet?

I used to be a mod on Nonsensopedia. https://nonsa.pl/wiki/Strona_głó It was a wikipedia-like thing, but with humorous stuff. I think it is abandonned now. There were a lot of garbage, but also some really well-written satires, that took a lot of writing skill of many authors to make. It is in polish, so most of you probabbly won't be able to read it. Reading it through a translator is not a good idea, because it contains A LOT of language humor and references to polish culture/memes/politics

There was also a similar project in english (Uncyclopedia), but Nonsensopedia was way better https://en.uncyclopedia.co/wiki/Main_Page
