I know I've asked this before, but it never hurts to keep brainstorming this. What are your top suggestions for sub stacks? (Hope that's a good way to refer to sub forums here) I'll start:

I'd love one for woodworking because it's the only thing I ever take pictures of, so I'd actually have some fresh content to post.

Hobby robotics and electronics! Been a hobby of mine since the early 90s. God, I miss Radio Shack from back then. Anyway, I 3d printed one of those little robot cats a few years ago and started writing some arduino code for mechanical walking, just to practice and see what that entails. Recently made a little camera turret so I could watch a family of blackbirds that moved in outside my bedroom window.

I bet there's a lot of users here that have similar hobbies. What are some of your sub stack suggestions?
