Today, Google announced an awesome new Google+ integration called embedded posts. Site owners can embed public Google+ posts on websites or blog posts with just a few lines of HTML code.
Embedded posts are a great way to share discussions and different points of view. Embedded posts are fully interactive so your audience can +1, comment or follow you. too. And bonus for Google (and clearly calculated) this is another way for Google to drive users to be active on Google+.
Images, videos and posts with links to a community are all supported.
Adding embedded posts to your website or blog is really easy. Simply find the post that you'd like to embed on Google+ and select "Embed post" from the drop-down.

Copy and paste the code onto your website. One part will need to go into the head section of your website and the other should go right where you want the widget to appear.
