Using a computer is often all about events and communication. Changes are always occurring, data is being received, tracks are changing, and news is pushed to you. All of these events occur in a bunch of different applications, and each has a specific way of letting you know that something has happened. It could be a Dock badge, a popup window, or even an audible alert.
The problem with this setup is that, as a user, you’re constantly bombarded with notifications from different areas of your screen, grabbing your attention in different ways. Growl aims to solve this by providing a central system for managing events. It integrates with a huge range of apps to provide a single, simplified way to receive notifications.
