He imports the taxonomy Christel created, kinda likes it and wants to use it for his site as well.
He makes some adjustments to it though, drops a facet (it's faceted) and a bunch of topics, and adds some topics specific to his site.
He starts tagging his new posts with metadata.
He adjusts his template. Now suddenly all his posts have not only links to related stuff on his own site, but also links to "More like this Christel's site". The automatically generated links are relevant and specific.
Meanwhile on Christels site links to related content on Pete's blog start showing up. Traffic flows. People find relevant stuff.
