As we all know, it is impolite to EMAIL, CHAT OR COMMENT IN CAPITAL LETTERS for emphasis. People tend to equate even a capitalized word or two with shouting. We're supposed to use bolding, or to write very, very skilfully instead.
I've accidentally found an alternative: Emphasis by capitalizing the FIrst TWo LEtters of the occcasional WOrd! There, I feel BEtter already.
