- The `h` problem is purely about moving your index finger, so I don't think it makes sense to talk about the bigram being popular. The relevant number is just how many `h`s people have to type in general
- Shortcuts staying the same: saying that there exists a variant of Dvorak created to do this too is a huge point in favour of Colemak. The point is so good that people modified a 70 year old layout to match it! How popular is this variant?
- Saying that Colemak is bad because of Vim, then saying it's good because of CapsLock/Backspace BUT that doesn't really count because you can also do this reprogramming with Dvorak: can you not also change Vim? Maybe this is much harder
