re personal compiler development playground: I don't see this for Nim 2. Nimony/Nim3 is more of a "playground", but rightfully so: he is creating a new major version of the language and aiming to improve the architecture of the compiler.
> He is also very difficult to work with and isn't very welcoming to newcomers
I don't have full context on the drama behind the fork, but I don't see Araq not being very "welcoming". Araq replies on the forums very consistently, replying to new-comer questions, which one might consider as "simple questions". Araq will state his personal & honest opinions, which may come off as abrasive or "un-welcoming" in your opinion. I don't agree with everything he says but that's OK.
From what I can tell the fork seems to be due to differences in direction of the language and w.r.t working together: differences in communication styles. But again, I don't know.
Personally, I see no reason to use the fork (Nimskull) over Nim, nor would I ever see any individual or company picking up Nimskull unless they were very deeply familiar with Nim (this is a small population of people). From a skim of the Nimskull repo, there is no website (there is a copy of the Nim manual), no forums (just some chatrooms), no clear documentation on the future direction, no documentation on differences for someone not familiar with Nim, etc. - why would anyone pick up Nimskull unless they knew Nim well? Please take this as constructive criticism. e.g. if any feature of the language/compiler/tooling is "better" or planned to be better: highlight it, summarize the long GitHub issue/projects discussions in a blog, etc.
