On a (SE) site I participate (along with other non-SE sites), I currently face the problem that users don't vote as much as I would like them to.
If they see content, they usually click it, read it and go straight to the next topic, not voting if the read content is good or bad. I want to encourage it so new users find more useful answers more quickly.
Right now, most questions idle at a vote count of 5 or below this so every question seems equally good. This seems to be the case, but it clearly isn't. As an expert on my topic, I vote on the questions that show effort and research. Others experts do this aswell. Yet, the "ordinary user" just drives by looking for the question he can answer not caring for the rest. This makes the search of high value questions and answers really hard.
I myself often don't vote on some particular sites because I'm not a real expert on the topic and I don't want to vote down content that actually is well-tailored for the site. I know that other members and users on my sites feel the same. I just don't feel educated enough to vote on specific content.
How can I encourage my users to vote more often? What can I do against the mentioned attitude towards voting?
