I think, when trying to help someone, asking for more context is a good thing. The examples that are given in the article are often things that arguably sound a bit more complicated than necessary (writing a windows app in assembly). Thus, the question is a valid way to establish a bit of context and by no means an implicit denial of the validity of what is being asked. "Because I want to know how it works" or "because I have reason to believe it is the only way it will work/be fast enough" are good replies and the whole thing leads on to a nice discussion (No not an exchange of tweets, a real discussion!)
