Now users of Google or frequent visitors may find articles and links related to your search. For example we can mention the search for "Windows 7" from now we will see results of people who speak on the subject, as our friends in Facebook, or other posts related to the theme that we have in our own Google Reader and even emails from Gmail.

For now, the option is in phase beta, like many other Google apps. However, we can activate it by following these steps:

1. Create a profile on Google.
2. Add social networking sites where we want you to look.
3. Enable "Social Search" on Google Labs.
4. Already in Google, clicked the tab "Show options" and in the left bar, select social. 

With that it will be enough, and we can see the results taken from some social networking and other Google services.
