I love the idea of Github becoming a more popular place for recipes. I translate many of the recipes I end up cooking into Markdown files[1], and love that Github renders them in a way that I can still share with my relatives.
The real win though is that with git for VC, you can update these recipes with the smallest changes and notes each time you cook it, knowing that each time you're getting closer to the perfect version of each meal. I hope this idea catches on enough that people might one day submit issues / PRs for each others recipes much like we do with open-source code.
May try this dough out myself soon since I'm still on a baking kick from all the Christmas cookies. Will open a PR / issue if I have any suggestions from the experience!
