Ah. That'll be my fault, I suspect ;-)

It's not stripping out the style tags, as an examination of the source for this page shows:

<span class="size4"><a href="http://undyingking.livejournal.com/tag/books">books</a></span> <span class="size2"><a href="http://undyingking.livejournal.com/tag/car">car</a></span> <span class="size2"><a href="http://undyingking.livejournal.com/tag/cats">cats</a></span> <span class="size2"><a href="http://undyingking.livejournal.com/tag/christmas">christmas</a></span>

The problem, of course, is that it doesn't have any definitions in the CSS for what those styles should look like :(

(Reposted using blockquote tags, rather than pre tags, in order to improve the resulting layout)
