That's great, and some people are better at writing useful comments than others. Not to detract from what you're saying, but > But if the comments are helpful to me, they’d also be helpful to someone else who didn’t write that code. this does not necessarily follow unless you've been extremely thoughtful in how you wrote those comments (which you may very well have been). That is, in fact, the issue most of the time — that comments are written in such a way that they serve to jog the memory of the person who wrote them, but are rarely of general use to anyone else.
