Interesting idea but to me it's definitely not the biggest missing feature. What Google+ needs is reddit or HN-style commenting, maybe not with downvotes (for whatever reason they don't already have them, even though they're on YouTube comments) but at least parent-child style commenting. It's been shown all over the web that it's impossible to follow threads of comments when they're all treated the same, Facebook-style, and Google employees should definitely know better as many of them use these sites. I suggested it in the "Send Feedback" area and really hope it gets implemented as it would be a game-changer.
