As a untrained "programmer," and one who can only limited time to coding, I often need the rehashed, rephrased, obvious answers pointed out. I am flattered that the more experienced monks take the time to show me stuff immediately that I maybe would have stumbled upon eventually. I'm not afraid of "learning to fish" but sometimes it's nice to be shown where the fish are in the first place. All that to say, I agree with those posters above who point out that a node of seemingly little value to you may mean a lot to someone else.
