Well, most everything I touch is in a Git repo :P but yeah, you mean on GitHub or something.

No, because Microsoft bought them. :P But you could host your own or use GitLabs or something.

I have some anxiety about putting half-finished stuff out there. I have come across others' half-finished projects and it's always a drag, especially when it's something I have been looking for and it turns out to just not work.

Yeah, it sucks, but if it means that it might end up in a more complete state eventually, then it will be better. Hell, maybe the anxiety will make you finish it faster. :P

Anything I put out there publicly has to at least work, at a minimum. The thing I've been talking about in chat is almost there.

Good. I'm looking forward to it.
