First, our apologies for a hiccup in our commenting system. Unfortunately, that hiccup was “expensive” in the sense that all comments before Saturday, May 13, were lost. We’re working to get them back [you would think it wouldn’t be that difficult, but . . . ], but we have a new commenting system in place that should be more robust and easier to use. During the installation trial period, there may be some ads showing up below the comments. Our apologies for that. Going forward, those won’t be there.
