FYI HN does edit out the "Why", but OP can go in and modify the title after submitting.

Maybe HN needs an "if num_words > 3" before the "delete leading Why". Or maybe an "if char_count > CHAR_LIMIT" before the "delete leading Why".

Or just don't. What a near guaranteed way to mangle the meaning of a title.
