Spending hours researching anything can be seen as a form of "geeking out". People can geek out on all kinds of things, like politics or sports or musical instruments or computer components or saltwater aquarium livestock (my weakness).
Dcurtis may or may not be a rampant materialist, I don't know, and it's really none of my business. The guy just geeks out on flatware. Seems a little strange, but whatever. Live and let live.
