Facebook provides many API and managers to work through a bridge of personnels informations, so facebook for me is a marketing and encouragerous source of developping for free 

You can use facebook to create ads regarding your services, different events, opportunities available at your firm and so on. You can also improve Google ranking of your website by writing different posts, creating events on facebook and including URL of your website as a link in those posts. It is also possible to set up an online payment gateway using the facebook.
