I like Gists, those fun-size Git repositories I fill with coding demos, scripts, and WIP markdown files. Today I learned you can edit these files locally and push them to a remote, just like any Git repo.
Grab your Gist URL:
Alter it slightly, and clone:
$ git clone email@example.com:5c61ee3fe0083.git $ cd 5c61ee3fe0083/
Make changes, commit, and push away. Your commits will show up under the
/revisions tab of your Gist.
