As demonstrated here: https://gist.github.com/bmcbride/62600e48274961819084 it is possible to define hooks to automatically create issues on a repo from responses of a Google form.
Doing so here could be a good way to centralize feedback on this repo, all by keeping an avenue for non-Github users to engage. This non-Github avenue exists (see form link added in a88c8e4) but those feedback aren't automatically incorporated to the issues on this repo.
