it's 2007 so there is some content stealing involved (not to mention that I stole the idea from a site that I can't remember)

register a domain and then code a script that does the following:


-get a list of all the domains that have recently expired
-check their pr, keep the ones that have pr1 or more, the rest discard
-go to webarchive.org and retrieve the content that was on the sites
-a month later* create subdomains on your site with the content that you have retrieved from the expired domains (you'll end up with a site similar to say blogger.com), add a banner or two on top and on the side - soon enough your site has gazillion subdomains with unique content and gets shitload of Google traffic
-spend the money on hookers


* Google might keep the content of the expired domains in its cache therefore the one month delay (no idea, just a guess)

all the best
