I'm part of a songwriting group that meets monthly and presents recorded songs. Last Sunday it was proposed that we could share what we're currently working on more frequently (in a shared drive). Tried this for a few days and am more secure than ever in the belief that it is more fun preserving some mystique around what you're doing, saving exhibition for the final product (or at least a product that is emphatically a song and not scraps), and not letting people see behind the curtain!!
