There are no bugs, just TODOs
I enjoyed Lukas Linhart’s Project Management article there are no bugs, just TODOs. I agree with a lot that’s there (a well-defined ordering for doing things, bugs and features essentially being the same type of task). I’m torn when it comes to “close old issues”. If the UI of the issue tracker does a good job of not shoving those old issues in your face all the time, there’s no real harm to them remaining open. It is sometimes the case that an old issue that didn’t used to be important can become important.
