Thanks to help from fellow blogger Rick who gave me instructions on how to do so, I have now returned to the default commenting system on Blogger. Here's how:
It's easy to revert back. Just go to your Blogger Dashboard and click on Google+ on the left side listing. Then, just uncheck the box that says 'Use Google+ Comments on This Blog'
With so many pages of info to read on the subject of Google+ I completely got lost in the maze. I don't mind posting to Google+ but do not want my Blogger page to change in any way as long as I can do so.
Anyway, thanks again Rick.
