Google announced two new G+ Platform integration today. As you can see, Google+ posts can now be embedded into websites and blog posts. Lots of other examples in the original blog post. Furthermore, Google Authorship is now automatically enabled for Wordpress-users who sign in to Wordpress with Google+ sign in
When you search for a topic on Google, you will likely see several search results showing "rich snippets" - profile image, name and number of followers on Google+ - for people who have set up Google Authorship for their content: A neat feature of authorship is that you can filter your search and see everything a particular author has written about the topic you search for by clicking on the author's name: Unless you go back to standard Google search, every search you do will be a search within that author's posts - which means that you can look around further in the writings of the author in question. Update: Apparently, this feature only works, if you search via google.com. You probably won't be able to use this feature, if you are using a local version of Google search
