I agree with you saying that Links are Queens and Content is the King. If you have both of these, then one would surely have a great PR Castle

But picking up random links from non relevant sites wont do you any good. If you want to start a link building campaign, then be very careful in picking up links. I would suggest that go in for highly relevant article pages. This ways you will not only improve your rankings, but will also bring targeted traffic to your website.
