Besides the frequently seen confusion about ownership and visibility, of comments published under Google+ Comments, some blog owners become concerned when they cannot find the expected dashboard settings and utilities.
Google+ Comments use community based moderation - and don't need dashboard, or email, based moderation by the blog administrators. The Blogger dashboard is a bit simpler, with Google+ Comments in use.
Google+ Comments are much simpler to setup and to maintain, than Blogger Native Comments.
With Google+ Comments, you have just one setting, in the dashboard "Posts, comments and sharing" Settings page.
Use Google+ Comments on this blog
With Google+ Comments enabled, you have one option, in Settings - "Posts and comments".
Everything else is decided, for you.
With Google+ Comments, everybody reading your blog - in your Circles or outside - can designate any given comment as spam.
Report spam or abuse
This option is available, on every visible comment, to every viewer, equally. A comment, published as "Public", can be moderated by people not logged in to Google+.
The blog owner (administrator) simply has no need to moderate Google+ Comments. Neither moderation related options, under Settings - "Posts and comments" - nor the Comments dashboard wizard, or Comments moderation email - are necessary.
The owner has no special ability to moderate - or even to view - all comments published against the blog.
Setting up Google+ Comments is pretty simple.
- In the dashboard "Posts, comments and sharing" Settings page, select “Use Google+ Comments on this blog”.
- In the dashboard "Posts, comments and sharing" Settings page, select an option for “Comment Location”.
- You’re done.
Now, get into your Google+ Stream, and start reading and resharing comments and posts.
