As you know, one of the main feature of SharePoint 2010 with Office 2010 is the social network.

I just discovered a new thing with this functionality: once you have created/updated your profile – especially adding colleagues, a new Contacts folder, called My Site, will be automatically created and filled with colleagues contact information on Outlook 2010.

This is done without creating any ‘PST’ file as it does when linking list/document library with Outlook.
