How do I setup comments, so the latest comment displays at the top?For a long time, the answer has always been "You can't.". This response does not satisfy anybody.
This option is finally here. With Google+ Comments, your readers can choose either "Top comments" (default), or "Newest first". The latter choice shows the latest comments at the top of the comments display.
If you are able and willing to use Google+ Comments for your blog, you can now provide this option, to your readers. This is in my opinion, the first unique and useful feature offered by Google+ Comments.
