@Chloe Sure, because it's explicitly a site for professionals, unlike other SE sites. FWIW, I didn't find it intimidating or harsh in the least, even at first. "It's for professionals, great, a minimum level of competence and effort to separate it from every other site on how to install a Server OS on the internet!"
Again, maybe that's just me being a crusty, jaded, bitter, cynical, cruel, sadistic, long-toothed BOFH, but I have trouble seeing any professional being scared off by "RTFF, dammit" comments in response to someone who's treating the place like Yahoo! answers.
