At LikeStream, we are big believers in the appropriate use of free and open source software. We gratefully use many such packages in the development and operation of LikeStream, and whenever possible, we give back by sharing some of the packages we have developed. At present the code we are making available includes:

• clojure-twitter: Clojure library for the Twitter API
• clj-oauth: Clojure library for oAuth
• clj-mql: Clojure library for Metaweb Query Language
• clj-facebook: Facebook client library for Clojure

As you can tell, we are huge fans of the Clojure language. We are also excited about Linked Data and the Freebase public database. An early prototype of some of our experiments is available here.
