This seems to hold true for most broad-interest sites like newspapers and magazines where comments can be downright awful, as opposed to sites like Slashdot with a self-selected and somewhat homogeneous audience. It seems unlikely that using only blogs for responsive dialog with authors and peers could come close to matching the feedback and community feel of comments such as we see here. Is there a technical solution, or is this a biological problem imposed on the internet?
Our engineering interns have started down a new path: Using Github from the beginning (I set the repo private), and, after a bare minimum is completed, flipping the repo public and continuing development in the open using Github. How do PO and Legal reviews fit in? How can we ensure we're not exposing ourselves or diluting our IP if we're doing semi-constant development, publicly, sans a heavily gated review process? What does everyone else do? Or does corporate America avoid this entire opportunity/entanglement/briar patch?
