Busy, busy, busy.

Completed XHTMLizing and MathMLizing everything, in addition to figuring out how to properly serve `application/xhtml+xml`

to every UA that can handle it. Posts and pages containing MathML have proper notices about it, with a link which directs you to the MathML section of the Colophon page where instructions on how to get MathML working reside. And now, for your viewing pleasure, a random mathematical equation:

$$f'(x) = \lim_{{\Delta}x\to0} \frac{f(x + {\Delta}x) - f(x)}{{\Delta}x}$$

Of course, this change means IE fucks *something* up. I mean, of ** course!** It's beginning to feel more and more like a natural law. Now, the aforementioned annoyance doesn't really matter much, it's just dead ugly. At the very top, it displays the following characters: ]>. I know how to fix it, but I won't. Why? Because that means more code. Those characters are part of an entity I've defined, namely

`&m;`

. I can use this entity in the `xmlns`

attribute which has to appear in every single `<math>`

start tag instead of the inferior (and long) URL http://www.w3.org/1998/Math/MathML.
