Using Wattpad as a Space to “Try Out” Stories?

I’ve been really curious about something for a long time. How fun would it be to use Wattpad to “try out” a new story idea? Though I’m still hard at work on TFN3 (don’t worry, folks), I’ve had a new story idea rolling around in the back of my head, but I’m not entirely sure how “big” I want the project to be yet. I thought it might be fun to create a great cover and just start writing on Wattpad and see where it takes me. If I like it enough (and other people do, too), I might just finish it...
