Jonathan Coulton’s career has taken off because he’s been able to tap into the geek market. NPR’s Frannie thought that he was a fluke and compared him 2 a Snuggie.  His business model has worked out for him and I believe that it can work for others also. Anyone can fulfill a niche today, but they have to use unique and creative ways to promote themselves.  I agree with what he said “Nobody has to sell out Madison Square Garden anymore to make a living.”
