Amazon.com

Today I’ve gotten lots of hits from someone, or some people, on the amazon.com network.  They’re all at the same IP address, but that’s likely a firewall IP; the hits are from multiple different user agents (different browsers and operating systems), so I tend to think it really is a few different people.  Most of them show up as direct hits, but some are from wiki.amazon.com (which appears to be a private host) with a query string about Red Hat Linux and mouse wheels.  Anyone from amazon care to say hey and shed some light on my confusion?
