SharePoint Community: The SharePoint Maturity Model with Expert Melinda Morales. Great interview and filled with a number of links I'm going to check out and post here if warranted.
Just as an aside, I try to link to everything I see http://www.buckleyplanet.com/Christian Buckley do. Besides the fact that he's clearly wicked smart, I have yet to see him do something - blog post, interview, webinar, whatever - that isn't 100% educational. You'd never know he was a vendor based on his content. Vendors of all stripes, whether products, services, integrators, could learn a lot from his approach.
