While I also find the comments more compelling than the links themselves, sometimes a thread degenerates and gets marooned on Pointless Island. It helps to be able to identify PI from a distance and hence stay away.
This is a tragedy-of-the-commons dynamic. Individuals can be well-intentioned and even mostly rational and we still end up with these suboptima. That's why it's necessary for someone like us to come through and do the vacuuming. Point us there and we'll do it, and send you a nice reply as well.
