Chatter Social Influence



One of the newest trends in social media is to measure a user’s “influence” within a social network based on the content they post and their interactions with other users.  This measurement is typically summarized as a “score” that makes the logic easy to comprehend as one number.  Chatter Social Influence will measure and score the influence of each user in a Chatter org.

Sites like Klout and Kred are the current standards for measuring influence on public social networks.  Klout keeps their algorithms a secret, but Kred gives some insight into how they measure influence.  It is up to you to follow their lead or derive your own algorithm that will reflect the engagement and quality of content that each user contributes.

We will be open sourcing the results of this challenge.


Develop a native application to measure and display a Chatter user’s social influence in the org. Each user should have a page similar to the screenshot above that will show their score, influential topics, and any other pertinent information.  Bonus points if you show the score on the user’s Chatter Profile page (see this blog post and GitHub repo for code). The best submission wins!

Must have adequate test coverage (75%+).


Upload all your source code as a zip (you can simply zip up your Eclipse project for convenience) and provide any documentation and/or instructions that are needed. Please be clear and concise with any setup instructions.

An SWF video of your application using Jing would also be helpful but not required.

A unmanaged package would also be appreciated as we will be open sourcing the results.

Your submission will be judged by a panel of peers based upon this criteria. If you would like to request an extension, please read Can challenge deadlines be extended for more time? on our FAQ. We do not want to grant extensions unless there is a valid reason.



Will the org this is deployed into have winter 12? I was thinking of trying to use some of the new JSON parsing features, but not sure if that is wise.

Can you put it in your docs and we'll make sure to test in a Winter 12 org. Thanks!

Exactly What platform or language is required or just submitting algorithm in doc format will suffice?

Take a look at the requirements above. It's for a native application written on their platform. You can sign up for a free Developer account at Check back for more challenges!
