Have any of you heard of www.movellas.com. It's a passions based creative community for young adults and teenagers focused on storytelling, based out of the UK, but most traffic comes from the US. Our goal is to make reading relevant and exciting again for teenagers and we think/we're starting to gather evidence that by embracing fanfiction and hooking young people in through their passions, a wider spread of teenagers are becoming interested in reading and writing. We have apps for android and iOS as teenagers spend most of their time on their phones.
Personally I was inspired by Roald Dahl, Jane Austen and Emily Bronte when I was younger. It's great to see young people engaging with some of the classics again through Hank Green's Lizzie Bennet diaries on youtube. I really believe that format and channel is key for engaging with this age group.
