I really dislike shortened names in programming and I'm not sure what I'm going to do about Bootstrap using col, btn, or lg. Probably switch to Foundation.
More that you have to memorise what the word is and what letters they're removing from it.
("Is it Lg, or Lrg? Err, hold on, I'll check...")
This, exactly this.
well, that's kind of funny, because I made this https://gist.github.com/zalew/6227522 for my work with Foundation. yeah, you should use Foundation, but because it's a better product, not because of class names.
