I definitely like getting reviews. I wouldn't post if I didn't! It's nice to know that people are reading and enjoying my writing. That's why I especially enjoy AC. Back in the day, when I had my old, crappy website, I never knew if anyone was actually reading anything I wrote. Now I do!
I also really like giving reviews and reading the author responses. I think it's really cool to be able to have that type of dialogue with other writers about their work. Plus I don't really talk with anyone about fanfic except you guys, so it gives me a place to put all my thoughts as I read. lol
As for flaming, I got flamed a few times back in the FF.net days. I wrote this pretty popular Aaron Carter story (that's actually posted under my account here LOL I don't have the heart to delete it) and I got flamed for it a few times, especially at the end when I killed off Aaron's girlfriend in the story. Oops. I also got flamed when I rated one of my stories R, posted the first chapter, and when there was no porn, people flipped out! LOL and even at 13 I was just like "Dude, the story is rated R. Not every single chapter! Let it build up!" Haha. Just dumb teenybopper stuff like that. I've never flamed anyone though. It's kind of a douchey thing to do.
Oh actually I did get flamed recently! I used to do this podcast about Avatar The Last Airbender, and this guy emailed in with a huge hate rant about me, saying I was the worst person ever and how the podcast had no credibility because I was on it. Annnnnd all this because I shipped two characters that he didn't. For serious. Come on dude! Anyway, we read the email on the show and afterwards I got a whole ton of emails from people saying I was the best part of the podcast and how they totally shipped the characters I did. That's not really a fanfic story but it kinda is because he hated me because of my love of fanfic for those two characters haha.
