Recently, I have found myself more and more frustrated and dumbfounded by the sheer lack of attention people seem to pay to their own writing. There are certainly circumstances under which I can understand using poor grammar.
However, over the last few months, I have encountered poor grammar in almost all situations from almost all types of people. I have seen sloppy, unedited writing in commercial marketing. I have seen and heard poor spelling and speech in professional situations and official communiques from various white-collar managers.
