It's entirely possible to think through what you're trying to do without writing the code comments. I prefer good old-fashioned pen and paper for example.
Of course, but you don't share those papers with us :) I like those kinds of comments a lot. In a good editor it's so easy to just scan a lot of code and understand what's what. You could look at something you or someone else wrote years ago, in different style, different paradigm, different language, ... and still have a perfectly clear picture of what code does in no time.
To each his own I guess.
