Google has already introduced Google+ comments for Blogger’s weblogs but now you can have them for your WordPress site. From the day Google+ introduced its comments for Blogger.com, WP plugin developers started posting various hacks and plugins for adding the same feature to WordPress sites but most of the plugins in WordPress Plugins Repository that enables Google+ comments to WordPress are broken. But now there is a new plugin called Google+ Comments, it allows you to enable Google+ comments in your WordPress based website.
Google+ Comments allows you to use Google+ commenting system that has been implanted on blogger.com unofficially on your self-hosted WordPress blog. You can check its live demo at http://www.cloudhero.net/gplus-comments.
G+ Comments system for WordPress seamlessly replaces the wordpress commenting system with Google’s. At this time Comments do NOT sync between Google+ commenting system and the WordPress built in one.
