I don't see Penflip as a replacement for Google Docs, but there are some cases where Docs breaks down - specifically when there are too many collaborators and when the content is too complex. Another interesting aspect is the need for multiple versions of the same core content - like a syllabus or textbook - with minor variations and modifications as needed. Something like this is unacheivable with Google Docs. For small groups working on a short research paper, Google Docs is great. But could you imagine a book being written with Google Docs, especially with multiple people? That'd be completely unmanageable. I love the HoTT book [1], because it's a great example of using GitHub to write a book with multiple contributors, and really illustrates the shortcomings with other technology [2].
