Abstract
The CCN paradigm perfectly fits with the OSN applications behavior and can help to save network load and reduce latency.
The benefit of using such a CCN approach compared to the current classical IP-based delivery and to the CDN-based solution, for the use-case of Twitter.

Concept of ICN
Focus on the content the user wishes to obtain instead of the server that provide this content.
Content should be named in such a way as to be independent of the location of the node where the content can be found
Nodes can cache the contents passing through it for a while.

Conclusion
Resulting from our evaluations, using ICN for social networking applications is advantageous for the network operator as expected but also for the end users QoE (Quality of Experience)
We plan to develop/adapt an OSN application on top of the CCN solution, to better suit native ICN functions and make large-scale tests on a real network
