One of the biggest complaints people had about Google+ was comments on popular people's posts taking over their streams. Today Google addresses those issues by rolling out the ability to collapse and expand comments. +Jonathan Terleski explains the simplicity of the function - click once to expand, click again to collapse.
Check out how the collapsed comments work in the screenshots below. It's as simple as clicking an arrow.
If you still don't like the way Google+ handles comment-collapsing, try out +Huy Zing's excellent Google+ Chrome extension, G+me. This extension uses a slightly different method of managing comments. You can do a "list" view, collapse posts in addition to comments, mark comments as you read, and do a mouse-over instant preview.
