i don't really see pointing out a few things in an otherwise squeeful review as "ripping to shreds." if there are aspects of the stories that really bothered me, esp. if i liked the fic a lot in general, i'd practically be lying if i only said "this was awesome!".

i actually think that the anon exchanges are an opportunity to [unknowingly] leave concrit for well-known writers. i think that a lot of people are hesitant to speak their mind if seemingly everyone else thinks this author is amazing. but in anon exchange, you have no idea who you are leaving fb for. also, if a review really bothers an author, they always have the chance to respond anonymously [i certainly would]. there's no rule against that.
