I like the idea of saving directly to Github. I'm using Github API for dictionary changes in my Chinese text translator that I'll release soon. The user interface is, indeed, beautiful. But that's not enough to make me use it. Notes on my iPhone can't be stored in a hierarchy of subfolders. In order to do that, I made my own notes app in PHP, but it's pretty awful. I plan to port it to JS+Github, but I have other priorities right now. Is it possible to only commit changes to a file using git, instead of re-uploading the whole file? I wish there was an easy way to append to a file without a download-append-upload process. Please teach me if you know how to do this in git!
