My pet peeve is Vim tutorials that start with "use hjkl to move around" instead of "use `set mouse=a` to turn on the mouse." In my opinion you need to make sure that you are very clearly disclaiming that you are teaching a harder way of doing things in exchange for incredibly small productivity gains that will be realized years in the future, if ever.
