Fantastic article, odd terminology—I think "pretentiousness" or something else might describe it better.

The author should read the book "The No Asshole Rule" if she hasn't already. I think it explores exactly this phenomenon in the corporate environment and describes how to avoid it.

Lastly, I think you'll find this kind of pretentiousness isn't unique to our field. Anytime you find a large enough group, the assholes will shine through. I'm all for calling attention to them and not letting them control the community though, so you have my full support!
