Go ahead. Every comment gets emailed to me, so I'll see it. So if you read something from a few weeks back and you want to let me know what you think, do it.
This isn't like a newspaper where you might seem crazy if you wrote today to the New York Times about their editorial of March 15, 1860: "your thought-provoking comments on Monsieur Thouvenel's statements on the state of the European nations has provided me with quite an eventful evening of enlightened discussion with my colleagues, each of us pederasts and debauchers. An earnest thanks to you."
Write that kind of stuff here and you'll fit right in.
