I just noticed that Is there a measure of code rot?, which was created in February 2011 was closed two weeks ago as a duplicate of How can I quantify the amount of technical debt that exists in a project?, which is a year younger.
Putting aside for a moment my annoyance at people seemingly randomly closing old inactive questions like that, what earthly purpose does it serve to close an older question as a duplicate of a newer one? If anything, it should be the other way around.
Turn away a bug if no reproducible test case exists?, https://softwareengineering.stackexchange.com/questions/45230/do-programmers-at-non-software-companies-need-the-same-things-as-at-software-com, How do you know you're writing good code?, and Code Smell: Inheritance Abuse are other examples.
