I love comments on this blog. If they are at all insightful they raise traffic here a lot more than a post will. Plus, I almost always learn something, which is even better.
However, comments in which you say (for example) “Hillary … be very afraid: [link back to your blog]” are of no relevance to any debate and do not add any value here. They are not differentiable from spam comments. If you are going to throw a link back to your blog, at least pretend to bring a new piece of information, or a new interpretation of a set of data, to whatever the subject matter is.
