Roger Montti offers an insightful post on link building for new websites in 2008. If you have no traction you need to find a way to buy/beg/borrow/steal attention. Use that exposure to spread content that turns people on / gets them excited / evokes an emotional response / ties in with their worldview and identity...and watch the links flow like wine.
Debra mentioned how she sometimes has a hard time telling people that their sites will not get links because they are boring. I actually enjoy doing that because it forces them to take some ownership over their own success (it is hard to drag a company across the finish line if you are an outside consultant - much easier to win if they are at least willingly walking in the right direction).
The way I teach people that concept is I remove them for their ownership role. I ask "If you did not own this website why would you tell other people about and/or want to visit it at least once a week?" Once they can answer that question honestly with something that is inline with their market it means they have something worth marketing.

Breaking the Digg Code - free guide to getting the most out of Digg, though if you market an SEO site it is not worth marketing it on Digg. The average small-minded short-sighted Digg user thinks all SEO is spam - they are a reflection of the dumbest and loudest parts of society.
