I'm Kimly, I live in Sweden and I really love fanfiction. :)
Sometimes I review, and I feel kind of bad that I don't do it for every story I read. If I feel strongly about something(good or bad), or if I have something that I believe could improve the story I will review in the middle of a story. Otherwise, I believe in reading the whole thing before giving feedback. However, writers asking for reviews like "I want a hundred before next chapter" or "Not reviewing is ungrateful" won't get a review from me, cause I believe that praise or constructive criticism is earned, not demanded. Why don't you all simply put things like "reviews are appreciated" or "please, I wasn't to sure about this section, any thoughts?".
Otherwise, I want to thank all you serious writers out there for sharing your work. You are the truly amazing ones.
Thank you for sharing!
