Although flames often get out of hand, they have a purpose in the ecology of cyberspace. Many flames are aimed at teaching someone something (usually in overstated language) or stopping them from doing something (like offending other people). Flame messages often use more brute force than is strictly necessary, but that's half the fun.
Netiquette does ask that you consider the art of flaming before pulling out the flame-thrower.
"This 'users are idiots, and are confused by functionality' mentality of Gnome is a disease. If you think your users are idiots, only idiots will use it. I don't use Gnome, because in striving to be simple, it has long since reached the point where it simply doesn't do what I need it to do." (...) "Gnome seems to be developed by interface nazis, where consistently the excuse for not doing something is not 'it's too complicated to do', but 'it would confuse users'."
