I can't think of a single good place to discuss technology tbh. There are some knowledgeable posters here (better than /g/ at least) but every other thread is non-tech pol schizo bullshit. It would be nice if all of that were consolidated into a single garbage dump thread, but I suspect the mods here are 100% on board with culture wars paranoia.
And yet the rest of the net seems even worse. Hacker News is full of annoying rich nerds and Reddit is gay as hell. My ideal community would be one that bans alt-right faggots, anime fans, trannies, and gamers. I wish something like that existed.
