This is will do great things for news.yc, temporarily.
People here to procrastinate have a lower average quality contribution than people here out of genuine interest. The average submission/comment quality will go up as they temporarily leave.
What will happen is that they will find some other way of procrastinating. The problem isn't that news.yc draws them too strongly; it's that what they should be doing doesn't draw them strongly enough.
Most (maybe all) of the most ambitious people I know waste more time than they'd like checking email and visiting news sites. Including me. I added noprocrast partly because I wanted it myself.
