Davey Shafik dissects the values of several tech communities in a new post on his blog.

Just like the programming languages that are the centers of our communities, each community has its own set of rules and idioms — they have a real life syntax. In my (almost) three years of being in a developer relations type role I have attended events in several communities and have observed how they differ from my primary community (PHP). As I’ve tried to understand those differences and the reasons behind them, I have had many discussions with members of many more communities also. After attending my first PyCon (US) I was struck by just how welcoming and diverse the community is and had many conversations trying to understand why this is. This is not what this post is about. This post is about conferences specifically, and how communities place different priorities on different things when it comes to how they run, organize, speak at, and attend events.
