On the Odoo website is stated:

"Social Network Integration
The Only Open Source CRM With Social Features Built-in

Bring social intelligence to your sales process. Gain insights from social media sites such as LinkedIn, Twitter or Facebook to find prospects easily and automatically load their contact data into your address book."

There is aLinkedIn module, but not working proper (overwrites existing contacts, no selection wich contacts of a company you want to add, etc...)

But how do i do this "Gain insights from social media sites such as LinkedIn, Twitter or Facebook to find prospects easily and automatically load their contact data into your address book"?
