It seems like it'd be fun, right? The only thing that concerns me is that, when I'm writing, I can't talk out loud or I'll lose my train of thought, so it'd be a totally silent stream unless y'all could hear my music. Also, given the way I write, I'd either be very productive or not at all which means it'll either be really interesting or very dull, probably. I guess I'm also slightly worried about being judged? Because you can believe I'll sit there rewriting a sentence 12 times and still be unsatisfied.
Edit: Signed up for Picarto and got permission to stream a bit of beta reading. Maybe I'll give it a try tomorrow morning.
