I should have given it more thought before enabling Google+ comments on my blog. The problem with this feature is that once enabled, a Google+ profile or page is required before any comments can be made on my blog. Anonymous and non-Google+ user comments are disallowed. With Google+ Comments enabled, I would expect some future comments to be loss as I actually have a few Anonymous user comments on my blog itself. This is definitely something that I do not want.
I spent something like 2 hours looking for a way to disable Google+ Comments on my blog. The answer is actually there at Google+ Comments FAQs but unfortunately it is not that obvious to me. A separate heading on "How to remove Google+ Comments on Blogger" in the FAQs would have been a much better idea.
