I agree in theory, but the problem is that everybody has their own personal "10 most interesting things right this moment" list, and they often don't match up even (or especially) among excellent programmers. So the fact that somebody isn't spending time with your favorite new toy doesn't mean they're not constantly learning, especially when the top 10 list is as ridiculously subjective as the one in the article.
