Google recently introduced a feature called "+1" where you can give what amounts to a "thumbs up" to any webpage that you visit. I have added the feature to ATP, so if you are on a page of the site that you like, click on the +1 icon and it'll increase the rank of that page on Google!
The first time you do it, you may have to create an account with Google. That step only has to be done once.
You can do it on as many pages of the site as you wish!
