How did you learn vi?

1) vilearn
2) vimtutor
3) Documentation (faggot)
4) Other

the problem with vim is that it appears to be a lot more complicated than it really is. vimtutor should not be your first resource although it is a good idea to copy and paste the bullet points after each section of vimtutor to make a cheat sheet.

your first resource should be Derek Wyatts video tutorials, when you see how simple it is in action it will be easier to learn

here is a sort of advanced video which also will give you an impression on how simple vim is:
