I think one problem is there are too many regulars on here seeing the same questions asked over and over. Every forum I go to regardless of envirmenet, topic, whatever.. whether it's health, diet, cars, animals..etc. New people just ask quesitons regulars see over and over without searching or reading stickies. This board is probably the worst because it's so horribly set up. So "regulars" end up having attitudes and "ridiculous" type messages just because they're sick of seeing newbies.
Not that it excuses it.. but that's usually what it is. I've done it myself on other forums because people just ask stupid questions when the answer is right in front of their face if they looked at some threads on the same page instead of just clicking "post".
