Some Jekyll templates have an easy integration with Disqus to allow users to leave some feedback, but I wanted to avoid a very (personal) data hungry tool.

Looking for alternatives I stumbled upon :star: Utterances, which uses GitHub issues to store the comments.

For a proper blog or social website this might be not the best option, but for technical websites that I tend to host on Github pages, why not?

Moreover, instead of authenticating via Twitter or Google, the user has to authenticate via GitHub. This to me is a feature :)

I tried the plugin in my Bioinformatics training website: see an example page here.
