Would you consider a "serious" third party candidate?

Independent and third party candidates get little to no publicity in the media. The Reps and Dems have developed a system that makes is more difficult to run as anything other than a Rep or Dem. Some of these "outsiders" have good ideas yet they are not given a platform on which to present them. How do you feel about a serious third party and would you support reform that would allow third party candidates a more equal playing field? If you do support the current two party system, why do you think an accepted third party would be bad idea?
