Google Plus Widget for WordPress
Software developer John Henson from PlusDevs has developed a handy, easy to use WordPress widget that displays your Google+ profile on your blog. The setup is quick and simple: Install the plug-in and drag the widget into your sidebar. Just fill out the form and you’re done.
You can also incorporate the widget into your template with only a few lines of PHP code, giving you the flexibility to place it anywhere within your layout.
