This would be nice for websites and services users want to get push notifications from. I get that html5 notifications should be able to do this at some point but there is still merit in having another way of getting stuff to your phone and possibly desktop.

Thing is, it does not offer push notifications. It's very opposite of that - the app seems to just poll the service with regular intervals.

Yes, but the interval is set in JSON, which is convenient. Besides, there is a manual mode.
