In today's world of social media, I think there may be better ways to raise awareness about a cause you are passionate about. A 19-year old PETA intern formally known as Jennifer Thornburg recently changed her legal name to CutOutDissection.com (yes, it's a real website) in order to bring awareness to her protest against using animals for dissection in schools.
Somehow I really wonder if CutOutDissection.com will still like her name a few years from now. I think the idea of associating yourself very closely with a cause can be effective (ie Bono and ONE or AIDS), but not to the point where the best option is to change your name to a bizarre website address. Social media and viral marketing seem to be the best way to get a message across effectively, especially if it has the legs to support itself through relevance, importance, urgency, or strong truth.
