Except what I find tends to happen is: 1. You google the problem and find results from stack overflow and some out-of-date blog posts from 4 years ago. 2. You choose stack overflow! 3. The stack overflow question most related to the one you have is closed as a duplicate. The duplicate's answer is: "look at this manual: link" but the link is to some .edu website that doesn't exist anymore, or is for version 0.7 on a unix system and you're working on version 2.5 on windows. In conclusion: 1. The world changes, so the same question may have different answers depending on when you ask it. 2. Having multiple different representations of a problem makes it easier to search for it correctly the first time, not harder (even if they all just link to one answer.)
