If you use Chrome and love Google+ but hate how messy the Stream gets, check out my new Chrome Extension: Plus Minus. It lets you easily mark Google+ posts as read. New posts in your stream show up normally and after you read a post, click the triangle next to the person's picture to shrink the entire post into just two lines.
Try out the extension and leave your feedback in the comments below.
