When I read Jeff's answer to this question today I had a minor brain tremor and quickly pulled out my trigger happy down voting finger to relieve the rage.
Here's a quote:
I think this site has too many questions, and specifically too many low-quality and marginally on-topic questions at the moment.
With this at the back of my mind while I went about the site today I came to the conclusion that Jeff is right (6 hours later I can't undo my downvote, sorry mate).
I admit there has been an extra effort over the past week by Sklivz and Oddt to close some of the worst questions. I am suggesting that we all get out there and help with the house cleaning and start flagging and voting to close. It only takes 500 votes to close and this site has plenty of people in that category.
We also have 27 people with 2000+ rep who can view flags and also see what has been vote to close recently.
We can do some CHAOS work of our own and start improving our questions and make this site a repository of high quality questions and answers.
