Check to see if Twitter is back up. I use it to let me know when we're no longer rate-limited and I can get back to working on Twitter stuff.

heyTwitterUmad.js

i = setInterval(function () {
    jQuery.ajax({
        url: 'http://twitter.com/users/show_for_profile.json?screen_name=dkordik',
        complete: function (data) {
            if (JSON.parse(data.responseText)["error"]==undefined) {
                alert("IT'S BACK BABY!"); //brings focus to the twitter tab!
                clearInterval(i);
                location.reload();
            } else {
                console.log("TWITTER? ", JSON.parse(data.responseText)["error"], "  " + Date().toString());
            }
        }
    });
}, 60000);
