Using Google To Serve Faster JavaScript

If you have JavaScript enabled then you almost certainly saw this message:

This browser supports JavaScript served with a mime-type of "text/plain".
This message has been served gzipped from Google’s servers.

This HTML page contains the following <script> reference:

<script type="text/javascript" src="http://deanedwards.googlecode.com/svn/trunk/test.js"></script>

Yep, I’m serving JavaScript gzipped from Google’s servers. Food for thought?
