Great article, comments are unfortunately too underappreciated. I sometimes write in (zSeries) assembly and I use guide comments a lot, on almost every line, to say what is the value that the resulting register will hold. I also sometimes use backup comments for code that I wrote at some point, but then it wasn't strictly needed, but I still believe it might become useful in the future. You could have it in Git, but then the information that this code is already in Git is lost.
