Not sure if "better commenting", or just another attempt to integrate G+ into every Google-owned property.

The part about floating "engaged discussions" to the top is interesting. One hopes the algorithm distinguishes between "ongoing informative discussion" and "blazingly active flamewar".

Can we stop claiming that Google+ can absolutely not be usefully implemented in other Google products?

Nice strawman. Did I claim at any point that g+ is "absolutely not [useful]"? No need to start white-knighting for Google.

Nice affirming a disjunct.
