I chuckle, but I am ever so thankful that you are on the lookout. Next time I'll use the spell check.
Even though I'm a grammar fiend, I make many, many, many, many, many, many mistakes (and forget to use the spell check too). I don't think I'm any expert with words. I do have a few pet peeves like misuse of lose and loose and affect and effect. I see those mistakes made all the time and by all sorts of people. BUT I make plenty myself, that's for sure.
