It's obviously not you, as others on the thread seem to be the same. Why do you get annoyed? Is it because they haven't paid their dues in the same way you have? If they use the camera I don't care what they spent on it, it is being used for it's purpose. It only annoys me when people buy stuff and leave it in a cupboard never to be used, whether it be a point and shoot or a 5DII.
My first camera was (still is) a 400D. When I first got it I didn't know why I should shoot RAW, what the difference in metering modes was, and why I should worry about white balance.
I didn't post on forums for a start exactly because of this type of thread. People who think that no one else apart from those with experience should be asking questions, or even posting on forums like this.
As for the sly dig at the Woman asking for help on which mode to use at a wedding. Grow up! She has 3 bookings on the back of her first, and will probably go on to be a successful wedding photographer, rather than sit here bitching on a forum about people annoying her.
Have you never asked a stupid question about cameras? Or tried to push yourself out of your comfort zone? To me that is the worst type of photographer. One who doesn't try through fear of failure.
