I will never adopt a google product again. g+ may be a total failure hangouts may be the less popular chat product
But for me and my kids this was the channels we used when they grew up. We have so much history in our family chat and so many photos shared on google+.
So now they just shut it down and don't even bother to migrate 10 years of my life to whatever is meant to replace those products.
We are a generation who will leave nothing behind.
