http://http://www.site-reference.com/articles/General/The-Misspelled-Domain-Name-Experiment.html An interesting article.
The link is bad in the original post,. here it is: http://www.site-reference.com/articles/General/The-Misspelled-Domain-Name-Experiment.html
This is of course an old idea. The article loses its appeal after the guy explains that his brilliant strategy still hasn't landed him a single sale.
That's an interesting article, if he went after serps and put some content on the page instead of a redirect he'd get alot more traffic I'd think.
