I use rails a lot and I don't know much about the methodology used, but some of my non-rails coworkers have said that they view a lot of rails guys as prima donnas. The DHH "fuck you" slide and Zed Shaw's massive flameout probably contribute to that perception too. Given that another big influence was ability to be a team-player then I can see how ruby guys are perceived lower on the list.
