For the individual, as I can testify, a brief grounding in semantics, besides making philosophy unreadable, makes unreadable most political speeches, classical economic theory, after-dinner oratory, diplomatic notes, newspaper editorials, treatises on pedagogics and education, expert financial comment, dissertations on money and credit, accounts of debates, and Great Thoughts from Great Thinkers in general. You would be surprised at the amount of time this saves.
