This just came to my attention and I already love it. I don't know if I'll ever use it for my own publication aspirations, but I've already pledged to support another author's writing project. I'm a sucker for good sci-fi, and the author I chose to support seems to know exactly what her goals are for this book/series, and how she wants to get there. You can find authors/books you want to support, or post your work and see how many people you can get on board.
I'm excited to see what authors do with this. People are endlessly creative, and I'm sure there are ways of using Pubslush that haven't been done yet.
What do you think about crowdsourcing/crowdfunding for the arts?
