Correcting the quote is silly, yes, but I think it's constructive to point out uses of the wrong word entirely. That's a far leap away from being ultra-picky about grammar.

Though it might make more sense to use "'ve" when correcting to emphasize that it's not a spoken vs. written speech difference, it's a transcription error.

* my comment was meant for other people reading your comment as much as it was for you. people soak up english in informal ways (such as reading stuff on the web) and someone might be led to use the wrong words. * some mistakes (and actual meanings) are obvious, others are more subtle. what else in the text conveys meaning that is different from the author's intent? * what purpose does it serve to say or write A when you meant B, outside of humor?
