Ask HN: Does anyone record themselves while programmming?

It's a good habit to keep worklogs when programming, some don't and their commit log and perhaps code comment might be it. But lately I have been thinking, what if I recorded every time I programmed, both myself and my screen session and spoke to the computer and captured my thought process. Sort of like folks do when screencasting but just for personal reference. I'm curious if anyone does so and if so, what are the pros and cons you have noticed?
