Perhaps I'm just a pessimist, but I have the feeling that if people should pick their own partners, I could imagine that all the established, well known artists would be picked really fast (or be the ones everybody wanted to collaborate with) and the rest of us would get the "left over writers" or be viewed as a kind of left over. (Yes, I know there should be a dash between "left" and "over", but the dash key isn't working right now.) I hope not, but that's what I fear.
