It's really hard to consider an answer to a moving target to be "complete". If the question was answered for Rails 3 but you're using Rails 5 and have the same exact question, chances are that answer isn't going to work for you. Now you have to chance that if you post the question again, is someone even paying attention? Is someone going to close your question as a duplicate? Is someone going to give you the wrong answer? Unless you're working with a dead technology, by the time the information is "complete", it's outdated. And I would consider much of the information on SO to be just that: outdated.
