or an IDE that just scans the code files, picks out the lines of comments containing "TODO" and put them in a list in the gui, so you see it all the time.

Or generate a compile warning instead of a comment. Then it will annoy you constantly, with no risk to production.

I think he makes the case (and I agree) that if you create a substantial number of TODOs and they manifest as IDE/compile-time warnings, they eventually become noise which you learn to ignore instead of fix.
