Myspace Marketing
Myspace marketing was once a great way for PR and SERPS but now they have a URL shortener that kills your direct links. You were able to blast comments and get an insane amount of back links daily but they killed it. IT is down but not gone. If you have a site that can be fueled by direct traffic like image uploaders or a cool content site that needs pure viewers to spread then it is still perfect. So SEO and PR pointless, traffic and spreadable content = Gold.
