Heh. If you'd searched, you'd have seen that we were nice to the first ten thousand people posting these repeat threads...
Try not to take it personally. There are a lot of topics that everyone thinks they were the first person to think of, but we see them every few days and get burned out trying to answer over and over again.
Hopefully, if Bitcoin really takes off there will be a million more people with the same question. I really did look around, read the Newbie section, etc and found nothing--so perhaps senior members might want to organize something to underscore that it is important to always be positive and informative.
It's just one opinion but for what is may be worth, I don't think you should expect new people to do tons of research in a forum with which they are unfamiliar...it's good that these things come into people's minds--and I think the expectation that most should or will self educate is erroneous. As an outsider--with a fresh point of view--as a consultant, if you will--I think for the good of the movement--senior members should either ignore dumb questions--provide links--but certainly *never* use a negative tone.
You should be glad this is happening and develop a positive strategy to deal with it.
For example I would encourage senior members to type up a canned reply (each different for each member) which can quickly be pasted into a response and modified a bit to suit the particular inquiry--the important thing is that the tone be positive, polite and informative--such as
"As a senior member of the community, I would like to welcome you. There are no dumb questions and we very much appreciate your interest. As you become more familiar with the forum, you will find that issues such as the one you just addressed has been discussed--and there are many good comments to ponder on the subject. Here is where you might want to go to research this issue:....."
You guys shouldn't be getting frustrated but rather see it as an opportunity--and develop a strategy to capitalize on the interest. If a junior member had made that comment I would not have taken much notice--but I think it is important for senior members to develop a policy for dealing with Newbies in a manner which will grow the movement and encourage participation.
Now where exactly can I go to get a full discussion of my particular question, please? If it is so easy to find, it should be easy to pass on. But when you look--try looking from the perspective of someone who doesn't know what he is doing and is completely unfamiliar with the subject and the structure of the forum.
