In late August, Rand Fishkin (Rand Fishkin is the CEO & Co-Founder of the web's most popular SEO Software provider; SEOmoz.) gave a free webinar called Link Building with Open Site Explorer. As is usual, Rand couldn't limit himself to just a bunch of Moz tools (he always feels a bit too self-promotional when he does that), so he ended up covering more than a few others as well. Rand also ran through a link building methodology and process that he has seen a lot of professional firms adopting lately, though their specific systems are more advanced and customized than what he illustrates here.
Nevertheless, here is the full video form along with the slide deck. Many folks may not have found the webinar in the free webinars section (bottom of the page), and I think this info is pretty useful for anyone investing in link building and wanting to use OSE.
