I personally think that if a question in a forum has been asked before, or has been discussed already, I would simply point it out for the thread starter to do a search. It is entirely possible people new to clubsnap are not aware that they've asked the 5th millionth question on whether they should get the tamron 17-50 f/2.8, if the kit lens is lousy, etc.
There are times I feel that clubsnap COULD do with an FAQ, but that would be directly spoonfeeding people with questions. I agree that those with questions should make the effort to look into their queries by themselves whilst waiting for replies to their threads.
All these being said, the attitude of some people who ask questions is deplorable. Granted, other members of clubsnap may not have been extremely polite when they directed you to do a search but new CSers need to realise that by being asked to do a search they are already one step on the way to finding their answers.
One way to improve our experience in the forums though, could be to phrase our questions such that there would be a general point of discussion. Instead of asking for lens reviews (which obviously, Google would be King), I try to see if other people could share their user experience on any lens I might consider buying, such as Calebk who is more than willing to share with other canonites the photos taken with his 35mm f/2 etc etc.
The only question that does irritate me: "Hi all I am looking for a lightweight DSLR combination with no need to change the lens and good image quality. " Such threads, I simply do not reply as I find it pointless. Don't want to waste my time and that of others, especially for issues where the answers to questions are extremely subjective.
What CS has provided me so far, is tons of good advice (when I've asked politely - as everyone should) and a good ground for learning more about photography. My technical know-how has also improved - this I believe we should all try and help one another along. But there is a line between asking what aperture causes diffraction and how to change my ISO setting (RTFM, as they say).
