When you are writing a page/post and you would like to backup the text, you can use this plugin. If anything happen to your server, you always will have the texts on GitHub.
This plugin can also be used for collaboration. You can easily see and track any changes done by other people + you can comment the changes on GitHub.

[gist id=546764 file=file.txt]
[gist id=546764 file=file.txt bump=1]
