First, I have not changed my comment policy – no moderation except for spam. But I have decided to force some kind of log-in on comments. I am going to try Disqus, and am specifically doing so during a quiet period in my blogging to have time to test it. Note that for a day or so, comments may disappear. I have them all archived, but it takes a while, apparently, to sync past comments with Disqus. We shall see how things go.
