YA Indie Carnival: Listopia Lists

This week at the Carnival we're talking Listopia lists. As I have absolutely no idea WHAT these are I figured some of you delightful readers could educate me. What is it? What's it used for? Do you like it? Let me know in the comments! Also fellow Carni  Amy Jones JUST released her new book and is running a contest on her blog. Go check it out and you can use the link below to find out what's new with all the other carnies.
