Earlier quoted context omitted.
Unfortunately, the barrier I faced with even trying VI is that you cannot discover any functionality intuitively. Exaggerating (but just a little) I could not even figure out how to type without someone giving me a tutorial. That was enough to make me stop.
When given a tradeoff between intuitivity and other benefits, vi almost always breaks against intuitivity. It's this design philosophy taken to its logical extreme.
Vim is extremely intuitive in its compositional behavior; I have never used "67w", but I know exactly what it would do because of composition.
I think "discoverability" is closer.
