What is YouTube planning to do to their comments platform?

In the wake of the Reddit, debacle Susan Wojcicki of Google raised the specter of changes to the YouTube comment system with a Tweet today during Vidicon 2015. In response to a Tweet from John Green and the subsequent discussion (see below) regarding YouTube comments, Susan Wojcicki Tweeted: "Yes working on updates for Youtube comments".

So far there has been no clarification of the statement, but the YouTube comments platform is part of Googles G+ social networking platform that some have speculated maybe phased out. With Googles substantial investment in G+ it does not seem likely that they will phase it out, but this does raise the question of what changes Google is planning on making and, more importantly,  how will that affect the YouTube community.

YouTube CEO @SusanWojcicki has been genuinely viewer- and creator-centric in her leadership, and I think YouTube is much stronger for it.

@johngreen That's great but have they cleaned up the cesspit that is the comments yet? @SusanWojcicki

@JustineLavaworm @SusanWojcicki no and it's the biggest problem on that platform imo. Need a redesign of the algorithm and better filtering.
