DestroyTwitter is a robust but compact Twitter application built on the Adobe AIR platform. It consists of a series of canvases that constantly update to keep tweets current and up-to-date using notifications that appear immediately after a new tweet arrives.
DestroyTwitter also features complete direct messaging functionality. Messages and tweets can be replied to with the original visible for quick and easy reference. A search function is also available to track anything that's being talked about.
