Gist is a simple way to share snippets and pastes with others. This app uses the new github API to provide a "send to gist" feature for most applications which have a "Send" or "Share" menu, making it very easy to share content. Snippets wil be posted to http://gist.github.com where they are available for viewing by other users.
By default gists are created anonymously - you can add your github account using Android's "Account&Sync" preferences or follow the instructions in the app itself.
You can also edit existing gists - Use "Load gist" from the menu, make your changes and upload.
