Feed Notifier is a Windows application that resides in the system tray and displays pop-up notifications on your desktop when new items are discovered in subscribed RSS/Atom feeds. By default, the pop-ups look like this.

Feed Notifier is what you get if you want real-time RSS/Atom notifications on your desktop without all the other stuff (clutter) that comes with most RSS readers.
