I've been using 's Google+Blog plug-in for WordPress for some time, to take my Google+ posts and shares and pull them into my WordPress blog. I'm a big believer in being able to aggregate my social media content back to my blog, where I can "own" and it's not subject to the whims of services going out of business or changing their policies.
He's now fully rewritten the plug-in as part of Social Media to WordPress — an effort that will be extending not just to Google+ but also to Facebook and Twitter. I've been assisting in the beta testing, and it's operating solidly. It's also a heck of a lot easier to install and update, and has built-in templating so you can control (in layout and with CSS) how the content will look on your page.
Good stuff, highly recommended. The free version is available at the WordPress site (http://wordpress.org/plugins/sm2wp-google-minimal/), and you can check out more at the SM2WP site (http://sm2wp.com/). There's also a G+ support community (https://plus.google.com/communities/112259832283760505227).
