It's the dvorak of git... Maybe more efficient but incompatible with everyone else and a very loud vocal minority.

You can find this pattern again and again. How many redditors say 120fps is essential for gaming or absolutely require a mechanical keyboard?

It's totally compatible though, and that's a big selling point. I use jj and nobody else at my work uses it and that has never been an issue.

Yeah I think that dvorak is a good example, too.

I don't get the mechanical keyboard one, though. I am fine with any keyboard, I just like my mechanical keyboard at home. Just like I am fine with any chair, but ideally I would have a chair I like at home.

120fps I have no experience with, but I would imagine it's closer to video quality. Once you're used to watching everything in 4K, probably it feels frustrating to watch a 1080p video. But when 4K did not exist, it was not a need. I actively try to not get used to 4K because I don't want to "create the need" for it :-).

I don't even like using "natural" keyboards despite the ergonomic advantage because it ruins my muscle memory when I'm on the (much more prevalent) "regular" keyboard.

I mean let's not be hasty. Mechanical keyboards used to be just normal keyboards when computers were still computers.
