I think the 196 community is the originator, though I already didn’t know what they were about when on reddit, I mostly find their posts confusing. From what I understand the (only) rule is that the post title must contain the word rule.

As someone not into the hobby (although I have a cookie cutter mechanical keyboard), what is the point of having that few keys? Portability? Otherwise i find it more cumbersome than efficient having to constantly use modifiers to access the full range of keys I might want to press.

Edit: this was meant as a reply to the guy with a 60% keyboard
