It is well known that downvotes can be used to improve overall site quality, by discouraging low quality questions and answers and users who post them.
But upvotes can also be used to improve quality, by upvoting questions you think to be of high quality, which both sets an example of a high quality question and encourages the users who post them to continue to do so.
So I therefore propose that we try and find question we really like, and upvote them generously, to encourage the high quality users on this site. We might have about 20 upvotes or so (not sure exactly) per day, so we shouldn't let them go to waste, so make sure you spend them, and spend them on great questions - even if they are questions from a while ago.
Let the up voting spree begin!
