Sorry, but I am using art in a very precise way. Advising to Webster , art, noun, skill acquired by Experience, study, or observation. As in the art of making friends. In the case casting is an art.
Yes, nook's do pick and choose what they want to listen to. That is a problem, as is the unwillingness of some to get away from a specific FACT they have decided is the key to everything. In my opinion this ultimately is due to a lack of personal experience. They try to replace first hand knowledge with "research" online or thru reading. This kind of learning does have a place but there is no replacing first hand knowledge gained at the range.
Chargar, your example is a good one. You had a problem with a very specific set of components. Ulu dis some asking, got the info to solve the problem, and FOLLoWED THRU. You dis not rely on others to solve a problem for you, you simply gained enough knowledge to know where to look for the answers. Ultimately the answer came thru testing and this allowed you to gain experience. That is the way to learn. In the future should you have a similar trouble I bet I know one of the first things you will look at!
