Nah man, that's the beauty of Reddit. Reddit isn't a single thing. /r/esp8266 is dope. /r/prusa3d is ledge. They figured out the mop/geek problem by just allowing arbitrary namespacing. Way better than any free community. Maybe Metafilter is better if you want to spend the $5. Dunno.

Lobste.rs tried that for technical stuff with tags and that engine is really powerful but the community never took off.

HN, of course, well, you know what it's like here when people of diverse interests and moral foundations are placed together.
