Again, my point is simply that the idea behind a unified social layer was sound. The specific decision that sharing and commenting were the same thing is obviously bone-headed.
Hmm. Facebook does it right: If you post something, comments on that post show up on your feed. If someone else shares that post, the share itself and comments on that shared post appear on the sharer's feed. No confusion, but I don't know that I'd call it a "unified social layer".
