In his own words, Seth says
Tamara recently interviewed me for UXPioneers. The only reason I agreed to consider it was that a good friend introduced us. Then I read her other interviews and realized that this woman had figured out how to create a very different kind of interview. It was a lot of fun. More relevant, as a reader, is that I actually learned something from reading the other interviews she had done.
I guess this is what happens if you ignore press releases, don't have a traditional editor and aren't trying to appeal to the largest possible audience segment. Either that or if you're a good interviewer.
