The most important programming languages is a concern. If you want to identify trends in web-app programming, web-stack, or even mobile, back-end etc., you need to forecast changes. This can allow you to make intelligent changes in selecting which language to apply to your projects.
Here in January 2014 Red Monk uses GitHub repos to identify the most important languages out there right now. I’m sorry I didn’t see this until 2014 is almost over, however I believe it’s still relevant in 2015. Here is a quote from the Red Monk article itself:
<quote>" While the appetite for up to date numbers is strong, the truth is that historically changes from snapshot to snapshot have been minimal. This is in part the justification for the shift from quarterly to bi-annual rankings. Although we snapshot the data approximately monthly, there is little perceived benefit to cranking out essentially the same numbers month after month."</quote>
