Need to add a second check in there against the occasional 404 that pops up.

if [ $? -eq "0" ] ; then
    page_changed=0
else
    diff wwdc404.html new_page.html 1>/dev/null
    if [ $? -eq "0" ] ; then
        page_changed=0
    else
        page_changed=1
    fi
fi

the 404 code looks like this, note there is a newline at the end that the gist trims

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>404 Not Found</title>
</head><body>
<h1>Not Found</h1>
<p>The requested URL /wwdc/ was not found on this server.</p>
<p>Additionally, a 404 Not Found
error was encountered while trying to use an ErrorDocument to handle the request.</p>

</body></html>
