Predictably downvoted, given the wording, but my intent was not to slight anyone. I'm genuinely puzzled about what could be so impenetrable to a fluent English speaker. I'd love to hear about it for that matter. Probably should have phrased it as a question, in retrospect -- the reason it is not is that I kind of expected that there were no good answer and that this was a "knee-jerk comments". Sort of the same kind of people who throw (sometimes literally) their hands up in the air and exclaim "I understand nothing about it" when you only mention the word "informatics" (well, the equivalent in my mother tongue).
