In my view, a large part of the learning curve for a novice is the ability to effectively communicate in the arena of interest.
If the arena is hardware then one must learn to communicate ideas or questions of design and theory etc.

This leads to the question, What is this forum about?
If this forum is strictly for the experienced to share ideas and have a common place of communication then those daring enough to post a question should know more and communicate more effectively on an expert level.
However, if this forum is open to help the inexperienced then the professionals should understand that much information would be missing in the question. It is here that some of the best opportunities exist to "teach" a novice. A light scolding (within reason) for lack of information will help the novice learn to be a part of this small community.

At my company, we always tease the interns for their lack of skill. It is in fun and is a useful tool in the learning process.

Remember that it takes very little time to respond with a request for additional information. Often, you will spark some brain activity in the questioner and open a world they hadn't seen before.

Personally, I get a great joy out of teaching and take pride in it. Remember the old saying: "Never a bad student, only a bad teacher".
Let's not be too hard on beginners, but Craig, we have to snap a little. It benefits the learner more than complete politeness.
