So if I post a link to a product there, and you click it and then buy something, I might get a small commission in the form of Amazon.com store credit.
I'm also working on doing the same with iTunes.
I'm going to be making a number of other changes soon as well. I need to clean up the blogroll, replace the Flash clocks with canvases, and fix the wishlist. I'm also working on a major project, based on some recent research I've been doing into combinatorial mathematics. That project will eventually get some attention here, when it's done. For now, I'm having fun learning things like "Ruby" and "Ajax" and "Twitter Bootstrap" and "Rails." More to come.
