"Be excellent to each other".
Party on Dude!
I'm still reletively new to Cosplay (Just over a year or so now) and personally took very slow steps when it came to progress; I kept on doing things that I could adapt clothes I already had for (..>_> -cough-Turks-cough-) And that was partly my own choice (I don't want to be able to showcase something if its not perfect) and another was because it was already clear to me that while the community itself seems to be so happy and friendly, there are a few individuals are just elitist (sorry to be frank.)
I don't think it just comes down to the competitiveness of cosplay, I think it generally comes down to people being elated above everyone else. Good cosplayers are one thing, but people are hero worshiped. However I do understand that some people are given this status not by their own choice either.
Again, its the minority that have this status, but it creates a gap, which creates feirce competition in the "ranks below" to reach the same standard. And by looks of things, its not just because of the standard of cosplay (a few friendly jibes in the masq queue isnt what I'm talking about here) its the full out slating of costumes.
If I got into cosplay right now, I don't think I'd be happy ever wearing something that I had made to a con for fear of being ripped appart by said elitists.
-shrugs- I have no idea if that makes sense to anyone else.
