Those of you who have presences on Facebook and Twitter have probably thought about adding your updates from those sites to your own. WordPress.org has a ton of plugins that help you add content from those sites to your own. Google+ Plus WordPress Widget is a simple plugin that does the same for your G+ updates.
The plugin grabs your updates from Google+ and includes them in your sidebar. Now this is a very simple plugin and does not have a ton of options. You do get the option to include your Google Buzz updates in your results too (as well as the number of stories that will show up on your site).
If you are too active on Google+ and want a simple tool to add your updates to your site, this plugin can help.
