The other side of learning about humanity and life through experience, fiction and art is learning about physical reality through science and research (if you're religious, or into reading your philosophy directly, feel free to add these to the list). And as such, both in support and contrast with many of my other hobbies, I quite like learning. Topics historical, natural, human, physics, astronomical, industrial, mundane, neat and collectable, avocational, pragmatic and practical and so much more. To this end, as of now, I watch youtube videos and do simple reseach – most often by browsing Wikipedia, or just going wherever google takes me.
When it comes to my Wikipedia crawls, I also enjoy improving whatever obvious small errors, imperfections and poor translations from my language I stumble upon. Sometimes I get the urge to become more involved with editing and help develop my favorite pages, but that has always seemed so impenetrable. I don't really edit other wikis1, but I salute those who do o7.

Other interesting wiki and wiki-like sites I've found include:
Tv Tropes, obviously
Liquipedia, for esports (go go Trackmania!)
wiki.gg and anything hosted on there (compared to Fandom, it's a godsend)
Wikivoyage, a sister project to Wikipedia focused on travel advice
The Fitness Wiki isn't really a wiki, but I've been using it for fitness info
The SCP Foundation and The Wanderers' Library, both hosted on Wikidot
AARoads Wiki, if you're really, really into roads (nothing wrong with that)
And since you've made it all the way here, let me show you to a special place..
