Facebook Stream API allows third party utilities such as web applications, websites and desktops “stream” Facebook feeds of users and their friends. Empowers these utilities to redefine ways in which the feed data is consumed and presented to users.

What exactly can be streamed?
Utilities can stream Feed elements such as:
-Friends’ picture updates
-Friends’ status updates
-Friends’ comments
-Friends’ application activities
-Shared media including video, pictures etc
-Profile Info of course
-Comments’ likes count
-Origination page for feed content
-Date and time information of feed item
-Publisher of feed content presented as either user or page

Existing websites/applications can leverage the stream to dramatically improve their utility by:
Increasing content and user activity.

Retaining more users by taking advantage of the re-visit factor because of guaranteed new and relevant content to the user upon visit.

Implementation of Facebook Open Stream API may mean increased average time on websites and applications as dynamic data is streamed and refreshed.

Valuable social “net bits” available at your fingertips. Facebook has done the work of bringing the millions of users, now tap into that plethora of information, draw what is attractive to your initiative and explore.

Advertising Boost
Increased probability that users will see an ad and click on it.

Better ways for developers to serve ads by mixing it with manipulated feeds.

Facebook might benefit from in-stream advertising with well targeted key words appearing in the stream.

Possibility of shared ad revenue from in-stream ads with third party clients and also form of remuneration for traffic redirection to Facebook.
