I'm not a fan and just find it annoying. I'd rather those opinions with the "What girls said" and "What guys said"

I had a look in settings in the notifications area, no reference to it1

No, that's part of the question structure now so there is no way to get rid of it. However, that section will only show your own Opinion, Opinions you have posted a reply to, and Opinions or replies you have been mentioned in. It's just a single place for posts that you are engaging with. Everything else is still under the "What Girls/Guys Said" sections.2
