It's not a clique. It's not a conspiracy. Some people are just not well liked. I mostly lurk but the regulars are pretty helpful. The complainers are like the same people in every workplace and school you've ever been to: in denial about why they are universally disliked and instead of accepting it or working on their whiny personalities, they blame everybody else.

Face it guys, you guys are just keyboard jockeys with attitude problems.

Mmmmm. Tacos, anyone?
