Don and I occasionally get complaints about our commenting system–not everyone uses FaceBook and sometimes, we are told, comments get lost. We’re sorry about both of those things, but I think we both much prefer the current system to the previous one. That system created a lot of what bothers Barry Ritholtz in this post , a post I empathize with. The comments should be a place for thoughtful disagreement and yes, even thoughtful agreement. If you use the comments as your personal playground, you should create your own playground instead, called a blog.
