I already asked you a question but another just popped into my head. I'm not going to name names but it seems that since your break out of fame with this series and the movies other authors have written stories of a similar format (diary entries full of doodles) but with their own original characters. Aren't you flattered? I think it's super cool.
Wimpy Kid does seem to have created a new genre. And yes, it's flattering!
