<p>Being a moderator on Stack Overflow (and sometime contributor here), I can definitely emphasize the importance of upvoting good content.</p>

<p>While voting for answers requires more detailed understanding of the question at hand (after all, voting on an answer is somewhat based on the veracity of the information in the answer), voting on questions doesn't carry such a high bar.</p>

<p>Questions imply that there is a lack of understanding on the part of the asker (and that's ok); what's important when voting on questions is whether or not the person put the effort into conveying their problem, their understanding of what it is they don't know, along with any other information needed to contribute to getting a quality answer.</p>

<p>This is why mods on Stack Overflow and other sites are qualified to instantly close questions when they don't have intimate knowledge of the topic; if we see a question that a user put obvious effort into creating with the purpose of getting a well-defined answer to a problem then it qualifies as a quality question and is not only deserving of staying open, but generally of an upvote as well.</p>
