<p>I agree that we should vote more often. However, we shouldn't up-vote on poorly worded questions. For example, this <a href="https://stats.stackexchange.com/questions/1708/variation-in-pca-weights">recent question</a> is pretty vague, yet at one point it had two up votes. </p>

<p>I tend to downvote poorly worded questions, and then reverse that decision once (if?) the question is corrected.</p>
