Hi Scott,
The purpose of Notifications is to give web page authors ways of notifying users outside the browser window. The notifications appear whether the browser has focus or is minimized, utilizing Growl on the Mac and custom code on the PC. This way, a user doesn't have to keep coming back to a web site to check on the latest mail or what not.
What are your thoughts on how notifications should work?
