1.	The first step was to do a Linux clone of one of our NT-hosted membership-based sites.
2.	We chose WhoIs.UserLand.Com because it's a simple site, but it's dynamic and keeps a list of remembered domain names using membership and preferences. If it performs well on Linux, it's reasonable to assume that our other dynamic membership-based sites will perform well too.
3.	It makes for a great A-B comparison. How do the two operating systems compare at deploying a functionally identical site? The answer is pretty clear. Linux runs faster. That's good, because that's what we want from Linux. A reasonably robust feature set so our sites can compete with the best sites at Yahoo, CNET, ZDNet, AOL, Netscape, etc. And high performance so our sites can scale up to serve millions of users.
