If you have a Google+ account, some will be happy about the ability of the commenting system to incorporate privacy settings within the Blogger blogs. You can activate this recently added feature by syncing your Google+ account to Blogger first. Just head over to settings and go to the Google+ tab on the left side bar.
There’s just one caveat: the comments will not work on private blogs. You’ll also need the latest Google+ update to continue. Once you’re done, simply just agree to the terms and conditions, and then you’ll see that your Blogger profile will then change to your Google+ profile that links both your Blogger blog and Google+ pass.
This might just pose a threat to Facebook.
