Again, it's a huge assumption on your part that they aren't willing to work or grow. Which might be a more reasonable assumption if we had a huge group of newbies demanding such a thing - but as far as I can tell we haven't. I think most of us that have been here for a while can pretty much spot the folks that are interested in learning and growing as photographers and the folks that want everything spoon fed to them, generally it's fairly obvious in the first post or two.
You are forgetting the part that everyone who posts on this forum has access to the internet which has the most information every amassed in human history at their finger tips. It's faster to google something than it is to start a thread on here to ask a question. It's just lazy behavior.
Now if someone says "I looked up DOF and have some questions about it's applications", sure I will be more willing to help. This at least shows some interest on their part.
