Citation needed pretty much pisses me off. It makes sense that if someone writes an article about Clinton going to area 51 to meet the aliens we need at least a citation. But for so much more, not really.
But the one that sends me into a monitor punching rage is when I go to stack overflow and someone asks a solid and very useful "opinion" question and gets shut down with some crap about the question being not relevant to the forum or some crap. Asking for everyone's favourite cheese would not be appropriate. Asking for which is the best library for accessing bluetooth on a raspberry is. Or which is the best 3D modeling software for making models in Unity.
My simple litmus test of how badly stackoverflow is now failing us is that I would say that nearly 80% of the questions I am researching have some answers, but the discussion has been shutdown.
What is funny is that not one programmer that I know wants these shutdowns. Not a single one. And as for a "programming" question being more relevant. They go out of date as well. Ask how to convert a int to a string has probably changed in C++ two or more times in the last decade.
To be even more specific, I would say the general opinion questions are some of the most profound. For instance it is very nice to know if you have lost your Oracle database connection. But more importantly would be a question such as, "What is the best programming toolset for making portable iOS/Android games?"
I would read through the answers and maybe I would discover that Qt has brought up their game and is the best way, or someone might suggest different environments they tried and could suggest one for a first person, but another for the candy crush sorts. It is discussions like this that have profoundly changed what I do. It was right here on slashdot that I have discovered many interesting technologies such as who I use for hosting, who I use for domains, which IDE I use and even which languages I use. Needless to say these weren't asked in the format, "How do I print something to the screen in Visual Basic?"
