I went with a space, but a comment is a better idea. I only mention the <script> tag in my article, for brevity, but I had the same problem with the <object> tag: basically any tag that can have content in html you had better close the html way (<tag></tag>), or IE will see it as unclosed and will not display the rest of the page after the tag (or do something else unexpected). Not a bug in IE (this time), which is correctly parsing the file as html.
