"Build it and they will come" only starts to work after you've pushed long and hard.
I think it depends on the site. I usually just put sites up, get some starter links and see what happens. Some sites never go beyond that and others will get tens of thousands of thinks on their own. Sometimes the simplest or oddest stuff seems to get the most links.
