If you haven't heard about this already, starting November 11th the company will start using your profile picture, reviews, and recommendations in their advertisements. They announced this a couple days ago and reflected it based on changes in their TOS. In the end, Google will be able to show a specific user's review for restaurants, for example, or if they follow a brand page on Google+ in their displayed ads on the web, which can be seen by around 1 billion users. Concerned? Luckily you can opt out. To do so:

  1. Head over to this Google Profiles page (you can type it in manually if preferred - https://plus.google.com/settings/endorsements?hl=en).
  2. Take a quick glimpse of what they have to say and uncheck the checkbox towards the bottom. It may be unchecked for you already, so leave it as-is if it's done.
  3. Remember to click the Save button.
You should be in good shape unless there's more changes on the way, but I'll make an effort to keep everyone informed.
