Interesting, I find sometimes I have to dictate into a recorder app to get the ideas out best, I suppose those end up being said in a lecture style a lot of the time, but that had never occurred to me.

So you aren't alone in that habit. I find listening to those notes something I don't do quickly enough but the number of times I've listened to an old one and heard myself say "... Have to watch out for X I suppose, anyway..." where X is a problem/bug that showed up later and was hard to track down has convinced me this can be a really useful exercise.
