I was part of a team that used web notifications as an experiment in sending live election results to people's devices:

It's a pretty fascinating feature set. You can attach images, update the content of an existing notification, attach buttons to perform custom actions, choose to make it silent or not... I think there is more utility than most implementations in the wild would suggest. One fascinating aspect of it for me is that you can do very time limited things (e.g. send election results) - users might be reluctant to download an entire app just for one evening of updates, but being able to send notification through the browser sidesteps that entirely (and more broadly, it puts a useful tool in the hands of people who can't afford native development).

That said, I agree that it's total madness that the default UI allows you to ask for permission on page load. We always had the prompt behind a button on the page and it worked great, so I think Mozilla have the right idea here.
