Analyzing GitHub, How Developers Change Programming Languages over Time

Have you ever been struggling with an nth obscure project, thinking : “I could do the job with this language but why not switch to another one which would be more enjoyable to work with” ? In his awesome blog post: The eigenvector of “Why we moved from language X to language Y “, Erik Bernhardsson generated an N*N contingency table of all Google queries related to changing languages.
