I read numerous complaints about how it worked, especially on blogs that had customized their templates in any fashion (which I had). So, I've turned off G+ comments and reverted to standard Blogger comments.
One downside to this is it appears any G+ comments have now gone the way of the dodo bird. I don't believe it was very many, but since I never got any notifications I really don't know.
So, if you had commented on a post, and it's now gone, my apologies. I didn't delete it on purpose, and I'm not trying to stifle the signal. I just changed commenting systems.
One of these days I may have to finally take the plunge and move over to WordPress instead.
The LORD bless you and keep you; the LORD make his face to shine upon you and be gracious to you; the LORD lift up his countenance upon you and give you peace.
Numbers 6:24-26 (ESV)
