I remember my senior year of high school every single essay I wrote had "comma splice" written several times within the margins, so I have to giggle each time I write a blog entry.
Because, I, am, certain, that, I, either, overuse, them, or, do, not, use, them, in, the, r,i,g,h,t, places.
Hopefully my point comes across nonetheless.
Or, if nothing else, some punctuation expert's eye muscles get a workout from all the rolling they do when they see my mistakes.
