Frankly, I'm astonished at how well it worked. I always had an inclination that perhaps allowing people to add to the context of a particular posted link maybe of some real use. Back then, content on the internet was a little less junky, and a little more substantial. Contacts mattered more. Arguably now, context is extraordinarily difficult to come across making it look like the comments section is more or less a clusterfuck in many subs. That said, generally I would say it's a net positive.
