That (thus far) people aren't rude.
There is a mix of people here from all sorts of backgrounds in development all over the world. It's amazing how similar our experiences are. We can learn from each other, not just about the languages we're interested in, but about the craft of being a developer.
I enjoy the links some provide to libraries, software or news items related to development that I might not otherwise know about. I like the bookmarks feature, too.
