This is fandom. People meet through a common interest. people connect. People become friends, and sometimes more. People form groups of friends. People do not say "Anything that's not written by us sucks." People are not, in general, exclusive.
If there is a hierarchy in any fandom, especially in puppyfandom, I didn't notice it. So either I'm dense, or people are letting themselves be intimidated by the way they percieve some authors' image.
I know whereof I speak, people. Like badbatz said, one tends to be too intimidated to feedback Famous Authors (or people perceived as such). I know, I've been there. Shit, I've had a feedbacker saying she was afraid to fb before because I was such a famous author. Which, um, I'm not. Nor am I scary or intimidating or exclusive.
So. In conclusion. Fandom is not Junior High. Take a deep breath and a chance and find out of the authors you're accusing of clickishness actually are. If so, then you can complain. But now, you're just being Junior High-ish yourself.
