"YES". I think people who enjoy the G+ layout for its visual appeal and ease of use will continue to do so, those who want to take more of a 'power user' approach (and are Hootsuite customers of course) will use that service.
hopefully it rolls out to more services like +Sprout Social
, if for nothing else than the ability to use your default social sharing/management app to share on G+. I think that's the key benefit.
