I don't get the author's pain point. `col-md-12` looks like pretty self-explanatory class name (or `medium-12 columns` in foundation). I mean, you're already writing HTML where `img` means "Image" and `div` means "arbitrary container", so unless you don't understand (or don't care about) the value of a 12 columns grid I don't see what's so bad about bootstrap's column names. Especially if you're already OK with having presentational classes in your markup.
