Normally, I wouldn't, but I did leave one comment this year along those lines. However, it was a really good fic except for the (incredibly jarring) beta comments left in and it was sometimes hard to tell which was the correction. So I commented saying how much I liked the fic (it really was very good) and that they should take out the edits. I felt bad, but I thought the author should know - they might have forgotten or sent in the wrong version or something. *shrugs*
