This flame results from disparities of knowledge and experience. The clueless newbie stumbles into a discussion group and starts posting stupid questions. Old timers and wizards then flame at will. This is a cheap flame. It's just too easy.
All cybernauts begin as newbies.
If you're an experienced net citizen, remember that you were a newbie at one point in your net career. If you're a clueless newbie yourself, check the next flame closely.
