To send a sensible Twitter message that is exactly 140 characters (including spaces and, if desired, a final period)

is the art of tiny poetry. It is a contraction of the words twitter and haiku. Because Twitter allows 140 characters or less, the twitku should take the form of 5 characters, then 7, then 5, separated by forward slashes. Spaces are free. Spaces don't count toward your 17 character total. All twitku's should be tweeted to @twitku575
