" Following the announcement of Google+ API deprecation scheduled for March 2019, a number of changes will be made to Blogger’s Google+ integration on 4 February 2019.
Google+ widgets: Support for the '+1 Button', 'Google+ Followers' and 'Google+ Badge' widgets in Layout will no longer be available. All instances of these widgets will be removed from your blog.
+1 buttons: The +1/G+ buttons and Google+ share links below blog posts and in the navigation bar will be removed.
Please note that if you have a custom template that includes Google+ features, you may need to update your template. Please contact your template supplier for advice.
Google+ Comments: Support for Google+ comments will be turned down, and all blogs using Google+ comments will be reverted back to using Blogger comments. Unfortunately, comments posted as Google+ comments cannot be migrated to Blogger and will no longer appear on your blog."
Hopefully it will have little affect on this blog, though my badge and link will be removed. If you are using google + then your comments on posts will be removed .. funny that approx 100 views a day but only one who regularly comments and another 2 or 3 occasionally comment, sometimes I think I'm writing to myself!!!
Anyway .. it's really wait and see what happens now, I will not be changing anything ... it will be google!
