You should be over the 'Youtube thing'. Many Google services employ commenting/voting/rating etc, handling these in different, separate siloed systems makes no sense. G+ makes a great deal of sense that its detractors are unwilling to admit.
As for the Youtube commenting system which all those who want to be derisive about G+ are quick to point to, they fail to mention how Youtube comments weren't that great to begin with and that the G+ comments they refer to are the ones rolled out immediately after the change, they omit mentioning and don't account for the numerous iterations the system received since then, and they haven't bothered to check on the comments situation since then because it would destroy their strawman arguments.
