Funny, one of the best things one can do to get faster with Vim is to switch CapsLock and Escape (though I know people who are still reaching all the way to that top left corner even after years of using it).

MathOverflow is a hosted instance of the SE stack, while the "Mathematics Stack Exchange" is part of the Stack Exchange network (started in their Area 51, "graduated", etc). The former is mainly for academics and professionals in the field, while the latter is more elementary and geared more towards the average user.
The complexity is actually one of the reason's I'm less attracted to American football than, say, soccer. In my experience programmers like simplicity and elegance, of which the NFL, with its large collection of seemingly arbitrary rules, has neither.
