YouTube enlists Google+ to fix the world's worst comments

This is an interesting and hard problem, and it appears that Google is solving it, in effect, by ensuring that nothing is truly anonymous, everything can be tied to the individual and traceable, and that you only see things that it decides you are probably interested in.

Is this a good solution? It's certainly a solution, and it might well get rid of (most of the) spam and trolls, and make sure I can talk to people I already know are worth listening to. But will I miss out on conversations I would be interested in, simply because I've never seen them?
