I think the more important question is why I've stuck around for the following two years and am about to send in my six bucks for another year's voting membership. There's a few reasons. First of all, I like the idea behind the N3F - bringing together all types of fantasy & SF fans, whether they're mainly interested in anime, comics, games, media or dead-tree media. Secondly, (and this was very important to me while the Sad Puppies thing was going on) the N3F was and is relentlessly apolitical, which is a pleasant contrast to most of traditional fandom in these decadent and depraved times. Thirdly, I am a sucker for responsibility, and the N3F gives me an opportunity to help rebuild an ancient and honorable fannish organization, which has had some Big Name Fans associated with it in the past and is working on doing great things to help fans in the future.
Hope this answered your question, and if not, I'm certainly willing to talk more about it.
