JGL talks about the concept behind HitRecord and is generally a BAMF.
ANYONE can join the site and post ideas for movies, music, art, photography, etc. on the site. And other users will give you feedback and if they love it enough they may help you in making that idea a reality. (Giuseppe Levitt gives a good example in the video). And the best part is that if the final product somehow generates revenue, everyone who helped make it will get money for it.
I'm signing up now and I suggest everyone check it out. There are so many creative people in this world, Hit Record allows talent from anywhere to collaborate and come up with great art.
