So I made a post earlier asking what small community people wished was on Lemmy and the top upvoted suggestion was:
One that shows big machinery. Like cranes, trains, excavators and stuff like that
So a made a sub with that topic and put some relevent pictures. I figure an XKCD style title would keep things light. Feel free to make this your own if this was your interest as I was just trying to plant the seed for some ideas.
r/SubSimGPT2Interactive is a good one, really cool community where you can interact with GPT-3 bot posts and comments in real time
