WTFs that I noticed:

1.  It exists.  Why do we need an HTML-based slideshow?  I could understand doing something like this in Flash so you could make it all needlessly snazzy looking, but all this "slideshow" does is essentially click the "next" link for you.

2.  The default speed of the slideshow is only 6 seconds per slide, but some of the slides have a full paragraph of text underneath.  I've been told that I am a slow reader, so this may only be a problem for me, but it's annoying none the less

3.  You can click the "stop" link to make the WTF-ery cease, but as soon as you click the "next" or "previous" link, the slideshow starts up again.

So, they took something that should have been simple and familiar, and turned it into something useless and frustrating.
