Yep really nice! I'm looking for something similar, a place where I can connect with other people who do hobby projects, and where we can meet and show off weekly projects and set goals. I know about https://www.startupschool.org/ of course. Would like something similar but not related to business, just to working on projects. Does something like that exist?

I've been looking for something like that too, for maths. Basically a group of self-learners, we set weekly goals (X pages or Y exercises from some book we'ee reading through) and then weekly meetings (online of course) for discussion of material and perhaps one person giving a presentation as well. Yours is similar but with projects instead. I've seen people using Discord and similar for things like these, I don't know if there's anything else.
