For me, learning vim is like learning an foreign language, a few hundred words (or few hotkey/:commands for vim) can get you started, but it's not easy to reach the level of native speakers, and some old rules in your language (for example, HJKL keys in vim vs the "natural" arrow keys) will interfere your progress.
Maybe I'm going to piss many people off here, but vim is not an user-friendly text editor. An user friendly editor should pop some kind of prompt when I pressed the first g/G key and show me what I could press the next, not telling me to read :help (which probably has the volume of a dictionary at this point).
Based on my 2 minutes with Micro and the information I read from it's `help defaultkeys`, the size of it's hotkeys are more healthy and manageable. So that's a plus from me.
