Thanks to the arcane magicks of Discover web producer Gemma Shusterman, this blog now offers the latest in commenting technology: the ability to edit your own comments! That's right: after you type in the comment and hit "Submit," for the next fifteen minutes you will be able to go back and change what you wrote. We expect that this will totally eliminate the appearance of typos or mistakes of judgment in any further comments. (Note that, in order to actually leave a comment, you have to click on the post title.) You'll also notice that the name of the author now appears at the top of the post, which is very helpful. We have a list of upgrades we're trying to gradually implement, in order to make your blog-reading experience as pleasant as possible.
