Google Reader is a great online tool that helps you get access to the latest new news dates and logs on the web.
Thanks to the Google Reader Indicator you will be able to know at the right moment when Google Reader's new entry is published.
The application is set as an icon in the Ubuntu index panel. Then, when you are warned to read it in the new Google Reader entry, it will appear only to you.
Finally, you can change settings to control the presence of Google Reader Indicator.
