As the person ultimately responsible for the Minecraft Wiki ending up in the hands of Fandom, it is great to see what Weird Gloop (and similar) are achieving. At the time of selling out, the Minecraft Wiki and Minecraft Forum cost tens of thousands of dollars per month to run and so it didn't feel too much like selling out, because we needed money to survive[1]. 15 years later, the internet is a different place, and…
I remember reading the Minecraft wiki back in the early 2010s, back when Fandom was still Wikia. It would have been much more appealing at the time than it is today - not just for the reasons you list, but because Wikia actually kicked ass in the early 2010s. It was sleek, modern, and easy to use. And today, it isn't.
Will Weird Gloop inevitably suffer the same fate? I hope not.
