CodePiece is a communication tool which is able to upload a code piece to Gists and share the link by Twitter. You can share a code piece and the description easily using this application. A code piece which you write will post to Gists on GitHub, and the code's description will post to Twitter with the link to Gists and the screenshot. Hashtag also can be added if necessary. If you write no code, it will be a simple text tweet without a Gist code and the screenshot.
