We don't want to answer questions with a just a link. But there are a lot of questions where a simple link to the documentation will suffice. I've seen several of these questions just go unanswered because someone will post a comment with the URL that answers the question. The particular example that prompted the question today is [this one](https://stackoverflow.com/q/20690840/945456) (which in this case also turns out to be a duplicate as well).

These question add noise to the community (show as unanswered, but practically speaking, are answered) without adding anything useful (a quick Google search and skimming the docs would answer the question). How should we handle these types of questions? 

* Flag them? You could argue they don't "demonstrate a minimal understanding of the
problem being solved" and therefore don't really belong on Stack Overflow. In this case, one could also close it for being a duplicate, but maybe we'd rather it be deleted entirely?)
* Answer them by summarizing the info in the documentation?
* Something else?
