After installing the Subscribers Text Counter WP plugin, I wanted a Google buzz icon with the number of subscribers. The following two step procedure will get your count too. Unfortunately, this is a static method. Maybe someone can come up with a way to pull the subscribers count from Google buzz.
Upload Icon:
Upload the icon of your choice through FTP or upload the image through the add new post media uploader in your WordPress admin panel. Record the location of the image.
Add the code:
Add this code to the widget: Make changes in the proper places in the code below. Place the code just above the last div tag. You may need to make adjustments.
