I really appreciate your feedback. I get what you mean, especially the part about saying "I" too many times. But the editor sent me the guidlines to submitting articles and in it they emphasize NOT to be too formal and maintain a casual style in writing.
You absolutely right about the readers pausing and not finishing the article, in the comments section it was clear that one reader stopped reading after the introduction.
Regarding the spelling of "Qt", I just went with however Trolltech spells it. In my mind "QT" would signify QuickTime.
