I have long been a fan of Peggy Noonan's writings, but I have missed out on many of her articles because I failed to remember to visit her site often enough and she does not have an RSS feed to her site as far as I can tell.
Now, I've just found Page2RSS. This handy services allows you to create links to sites that do not have a feed and which you can use in any feed reader. You simply enter the URL and out pops the resulting feed link. Very useful!
