[jQuery] Hmm, am I doing something wrong?

Normally that's how I work. But seeing as how the tutorials and the code itself says:
* To use, place this HTML into the <head>...</head> of your web page:
* <script type="text/javasript" src="http://jquery.com/src/latest/"></script>
I thought I'd ask if John had an opinion on the matter.
