Mhh a download of payed software. Too bad, with an open model and proper integration of social media this could have been a billion dollar start-up and one of the things that could take on Hollywood in a couple of years once their tech has matured a bit (no this won't compete with Michael Bay and yes most movies will be crap and/or porn, but it now means that every half decent writer will be able to gets or her work on the big screen).
The great thing is that it enables writers to prototype their work. So now, people can have screening parties and do crowdfunding for movies. I think this is great from that perspective.
As someone who's about to make my first short film with a friend soon, I'm going to throw the script into this and see if it's absolutely horrid or not. Might be useful in spotting really obvious mistakes.
