When this stack exchange started, we voted early and often. Halfway decent questions got 3-5 votes, good ones 8-10, and excellent ones 15 or more. Nowadays it's rare for me to see a question with 5 votes on it. What's happened? There are clearly more active users than this, so why aren't you voting?
I know that recent publicity has flooded us with a lot of low-quality questions that generally produce a feeling of "meh." But this is not the only issue here. Take a look at this question by makerofthings7:
It's a good, interesting question that was clearly researched ahead of time, and I know you all saw it because makerofthings7 even posted a bounty on it so it has been sitting in the "featured" area for 3 days! Yet as of right now there is exactly one other vote on it besides mine. We can do better.
The other thing I'm seeing a lot of are questions that have several answers but no votes, which doesn't make any sense at all. If it's worth taking the time to answer, it's definitely worth one single extra click to vote on it! And if the question is genuinely so "meh" that you can't bring yourself to upvote it despite the fact that you we believed some kind of answer was possible, then instead of answering it edit it to something you would actually consider a good question, and upvote that!
On the other side of things, if it's not worth an edit, not worth an upvote, and not worth an answer, downvote with a comment. The addition of the comment can prevent a meh-poster from feeling unfairly "punished" and it might motivate them to edit the question themselves if you actually give them an idea of how to fix it. Downvotes help people, not hurt them.
If you still need encouragement, consider this--the electorate badge is one of the easiest gold badges to earn and so far only 6 people have done it. Just think about it.....shiny. If you're on the site anyways, might as well turn a few easy clicks into a nice bright yellow circle. Don't you wish you were a gold-badger?

p.s. Lohoris, none of this applies to you. You're awesome.
Edit: One more thing
I also want to remind people that you can upvote while voting to close as duplicate. Sometimes you'll run across someone who has phrased something really clearly but just didn't recognise or understand how another question gave them what they needed until someone else pointed it out. It's worth rewarding these people's participation in the site, especially if you want to drown out the meh-questions in the future. Just because a question turns out not to be needed doesn't mean that the person wasn't making an effective contribution--good phrasing on a duplicate question helps our search engine visitors find the content they are looking for, and that's worth rewarding.
