Mix it with rule 34 and you got things like WikiFeet or some Czech site which is literal database of nude scenes in our whole cinema history (sorted by movies, actresses and director including screencaps of course).
The thing that makes me double-take is the consistency, breadth and depth, and liveness of the tag system.
Like, I want this level of OCD, meets del.icio.us, meets HN.
Them, knowing more than you might assume: "OwO what's this?"
You: possibly now a furry due to inversion of plausible deniability
On a more serious note, within the circle of my friends this falls into "prank link" category - rickrolling etc.
Rule34.xxx, gelbooru, danbooru. Truly a wonderful world we live in!
It's a pleasure to speak with you. Conversation is a sacrament (and an art well beyond me). I hope to capture what I love about the web: people who make life worth living.
For those who haven't already seen them (these people are rockstars), I'm also a huge fan of my beloved: https://wiki.waifu.haus/, https://sphygm.us/, and https://kickscondor.com/ - these treasures inspire me quite a bit.
Kickscondor was actually the person who first led me to your site - I enjoy their content too. I'll check out these other two as well, thank you!
Gwern's also a really interesting and passionate Internet Person, though I know you've had some interactions with him so I'm just mentioning him for the benefit of others. I've run into a couple of other treasures in my time but I'm not consistent enough at maintaining a PKM to have them to hand sadly. Maybe someday I'll start a public personal wiki of my own!
