Well, it's official - Google Authorship is done and gone. First they removed author photos, and now all author info will be dropped from the SERPs completely. According to Google, the "rel=author" markups signifying authorship will not incur penalties - they'll just be ignored.
In a blog post shared last week, Google's John Mueller explained that authorship information simply has not been as useful to Google users as was hoped. In fact, it was sometimes even viewed as a distraction. Google maintains that site traffic won't decrease as a result of authorship removal.
