title: Notifications across all browsers
body: <p>Are there any sort of notification system that works with all major browsers? I know chrome has their Notification API, Safari has push notifications and IE has pinned sites but is there some more general way to show notifications? I did find <a href="https://github.com/ttsvetko/HTML5-Desktop-Notifications" rel="noreferrer">https://github.com/ttsvetko/HTML5-Desktop-Notifications</a> which uses a combination of different notifications (though I still can't seem to get the demo working in IE).  </p>
