It is all about good, original content. If you have that, folks will find your site and link to it regardless of a link campaign effort. This also does not happen overnight. It could take years. Everyone always complains about how google puts so much weight on the age of a site, but what many folks don't think about is that great sites and great content don't usually happen overnight, it takes time.

Links to good sites related to your topic is a good part of any informative website. Sometimes visitors go to a site on a regular basis, just because they have such a good collection of links to sites that interest them. Sometimes putting together a good list of sites that people will want to visit can be a good portion, or even all of, the content of a website.
