I'm glad you enjoyed my answers; however, I am never intending to come across as smug. It is difficult to get across subtleties in an impoverished text-only medium; it has certainly been my experience that instructive and constructive criticism can easily be read as smugness. It's also been my experience that trying to deliberately make it sound less smug often just turns it into sounding like condescention. Text-based communication of technical issues is a hard problem and I do struggle with finding the right tone. Thanks for the feedback.
