That is exactly the reason I don't, normally, preach, chastise, or rant. No one is perfect, especially me. Usually, as soon as you point out someone's fault(s), yours come glaringly clear soon after. That said, a mis-spelling here or there is a matter of single events that may or may not occur because the author doesn't know the correct spelling. Could be a typo; Could be a "Senior Moment." (Besides, I think they used to spell it with an "n" when I was in third grade


) Mis-use of homonyms, on the other hand, in my opinion, occurs because the author truly never learned/retained the correct meaning of each homonym. And that, unfortunately, works to harm the credibility of the author IMHO.
