First of all, I'm not exactly sure why Nahmod's article was even advertised on this forum. Clearly it was bound to stir up controversy and provoke tempers. Why get into all of that?
I find it impossible to talk to anyone at the fests as they want to be alone or with their clique of friends.
Everybody that I've ever met at a DS event has been quite friendly; however, I have seen fans who tend to stick in defined groups. I don't interpret their behavior as deliberately rude though. As I see it, these people have known each other for a long time and are accustomed to socializing with one another. I love to meet new people at these events, but when I go to a Festival, I naturally want to see my friends and find out what's going on in their lives as well. It's generally easier to be around people whom one has known for a few years than those met a few hours earlier. Rather than feeling slighted or discouraged, I feel more determined to continue my participation in fandom and even to broaden it. It takes time and patience to find a niche, but from what I've seen, the effort pays off in valuable friendships further down the line. This is just my opinion of course, but I do hope that you'll give the fans another chance.
