Arch Linux Elitism
It's been said that Arch Linux users are elitist. This mostly stems from Arch's keep core simple principle, and an expectation that users should do some research and checking before posting support requests in their forum. (And really, is that too much to ask?)
Now Arch isn't Ubuntu or openSUSE which are designed for beginner Linux users; instead, Arch is designed for intermediate to advanced users, or those who are willing to learn Linux. As such, there is a lot less hand-holding for new Arch users, which can be interpreted as elitist or pretentious.
I don't personally feel that Arch is elitist, but judging from this comment in the Arch forum I can see why people would think their elitist:
...And about the notion that dumbing-down the installer would bring more users, then we for sure do not need those kinda users which such a change would bring, and we in fact allready have much to many of them imho!
Although that's just the opinion of one person, it does reflect on how people perceive the project.
