What I like about stack overflow was that it was a great resource to go to when you cannot find the answer to your question by spending some time searching the web. I think that having questions on here that are already well covered, such as "What does f-stop mean?", "What is the “Rule of Thirds”", "What do lens acronyms mean?" do not benefit this site and are redundant. It will encourage people to just ask a question on here rather than trying to find the answer themselves and will not add much knowledge.
I am in favour of an addition to the FAQ to request that people search the web generally and not just this site before asking, and that we should be closing such questions as off-topic. What are other peoples opinions?
