Due to popular demand from readers and to the increased discussion on the site, I have added a new feature. At the very bottom of the sidebar, you will note that there is now a list of recent comments that you can link to. This way, readers can follow not only the blog postings themselves, but also monitor the discussion going on.
In the past, it was difficult to engage in a discussion on older posts, because readers would not know that someone had posted a comment on an older post. Now, however, readers can easily see where the commenting "action" is, so that they can participate more easily if they like.
