More in reference to the comments here than the actual article, but TODOs in the comments can be used to transmit what I find to be useful information: $THING was on the writer's radar, but $THING is not handled (correctly or not) in some non-obvious manner. If your project uses them to indicate e.g. things that can not be merged into master, then obviously that's one thing, but when they're simply comments, the hate here seems misplaced. Other than (maybe) redis, I don't think I've ever seen code that did not have "potential things to do" that would have been nice to see commented.
