Does it work with URLs?
Buy a new domain or an expired one cheap, set up a word press blog or whypark site, then use backlinking software (SEnukeX, submitteaze etc) to increase the PR.
After a while when it has a lot of backlinks, its been suitably crawled, and google has FINALLY done a new PR update - relist the domain name and sell it for a profit.
It may not be quick money (taking a while for a lot of back links to get crawled, and google to do PR updates) but in the mean time you can have an affiliate site turning a few $$s as well.
Does this work? Just how far do you need to take the marketing effort to see a decent return?
