I find it so tricky, too. With the maintainers that I see struggling, it's rarely a lack of contributions that fucks them up, but rather a lack of maintainers. And they can't easily onboard other maintainers, because:
- there's hardly anyone willing to invest enough time into your project to be a particularly helpful maintainer.
- everyone's just strangers on the internet, who may or may not want to ship malware as part of your project.
Like, I even have a friend who's excited for a project that I'm building, but so far, they're purely cheerleading (which is appreciated), because they do have projects of their own that they find fun, and in particular also a life outside of programming.
I do not currently struggle with maintainership (because I haven't announced my projects anywhere publicly 🤪), but yeah, it just feels like it's asking for a lot, if I were to try to get that friend on board. In particular also, because not many aspects of maintainership are fun.
