Gists provide a simple way to share code snippets (in this case, notes) with others. Every gist is a Git repository, which means that it can be forked and cloned. If you are signed in to GitHub when you create a gist, the gist will be associated with your account and you will see it in your list of gists when you navigate to your gist home page. ↩︎
One small suggestion (and I realize it may be too late) would be to name it either "Publish to Gist" or "Gist publsiher". Even having just installed it, when I went to try to find it on the plugin page I didn't think to look for it under "Joplin". Every plugin is for Joplin.
Anyway, this is a great plugin. Thanks so much for making it!
Using it more a use-case that's very previous to me is revisions. Since the plugin updates the gist, you now get a nice git diff with differences from the different versions. It's a bit easier to deal with than the built-in Note History
