My own issue with this method is trying to avoid sounding like I'm vying for brownie points by demonstrating knowledge after asking (what to them might be) a rudimentary question, especially so if my "update" is partially incorrect. It is to the point where I won't show someone I am aware of something simple they have just pointed out to me. Which either is something the author of the blog would condone or I have misconstrued in which instance it is useful to look like you have less understanding than you really do.
