How do I enable Google+ Comments?and, alternately
I am trying to change our blog to private - but no options come up under "Permissions" - "Blog Readers". There is no "Edit" link.These blog owners are discovering that, though one of the earlier publicised features of Google+ was the ability to distribute a substitute private blog posts feed, a private blog comments feed won't be offered.
As we've discovered, and written about, various deficiencies and problems involving Google+ Comments, Blogger Engineering has been busily disabling some dashboard settings, to prevent use of incompatible blog features.
With Google+ comments enabled, you get a notice under Permissions.
Under Settings - Basic - Permissions, we see
Google+ Comments enabled. Learn moreIn this case, "Blog Readers" shows as "Public", and there is no "Edit" link to designate readers.
With a private blog, you get a notice on the dashboard Google+ page.
Conversely, for a blog which uses Blogger Native Comments, and made Private, we look under the dashboard "Google+" page, and see the unpleasant advice.
Google+ Comments are unsupported on non-public blogs and blogs marked as containing adult content. Learn moreIn this case, the option to "Use Google+ Comments on this blog" is grayed out, and the check box is inoperative.
We are advised to use Google+, to distribute private blog post content.
Long ago, Google+ was recommended as a way to distribute blog post updates, for private blogs - making up for Blogger's inability to provide newsfeeds for private blogs.
It appears that the benefit of Google+ only extends to posts, for private blogs. Private blog posts can be distributed using Google+ - but private blog comments will be limited to using Blogger Native Comments.
