Now you can add your own seal of approval to your Google search results with the new +1 feature, introduced by the brand yesterday. By voting +1 on a result, users can show their contacts in Gmail, Google Reader, G-chat and eventually Twitter which results they found helpful. Each result will show which of a user's contacts gave it a +1. Google also plans to expand the feature beyond search to various sites across the web.
