I'm a bit confused really. I noticed if said question is similar to another, mind you I'm saying similar, people mark it as "Exact Duplicate". I'm confused, so I ask: in as much detail as humanly possible, what's the policy on marking questions as duplicates? Or asking features as duplicates? or asking a question about something similar to another question?
It seems that when a user posts a similar question but asks it in a completely different way, the question and answers should be linked. However if someone asks a similar question but asks for more detail, or more information than a previous question has supplied that either its a valid question, or a "Jump-Off" question.
However, I do think it is rather silly to link similar questions by their title. Especially when pertaining to asking a feature. One feature may be declined for a reason the new proposal solves. Makes sense. Anyone participating in Meta has made a conscious choice to share their opinion and each opinion should be valued. If it's in Meta, there is a reason someone is asking for it. I want to know the policy to avoid any problems, before I get turned off for helping Stack Exchange in general.
