I really enjoy doing this as well. Are you aware of any resources or metrics (number of contributors on github, etc.) to find which projects are "well crafted" in X framework/language? Perhaps I overestimate how much risk there is in learning idiomatic practices from a project which is not actually all that idiomatic. I like the assurance that what I read is quality, especially with frameworks or languages I'm very new to where it can be tough to tell.
