Redirect Comment Display and Management to Google+ or other online service.
This plugin redirects users to a Google+ post where all comments for that post will be displayed and managed. The plugin displays a "Comments for this post are located at..." message at the bottom of each post with a Comment Redirection Url property, entered on the post's Quick Edit form.
Services like Facebook and Google+ embedded comment plugins that display comments on your blog are awesome. This plugin is for those who want to move comment display off their blog completely, yet still make it easy for your visitors to comment if they wish.
This plugin also helps centralize a post's comments and tie them to a single permalink. Google+ embedded comments will display on your blog and below the post where comments normally appear. However, when a visitor posts a comment it creates a new Google+ post and thus disperses the post's comments across multiple posts on Google+. The Comment Redirector gives you the ability to control the conversation and direct it to a single url.
