This is fascinating as it goes contrary to the Google Trends data on a number of languages. For example google trends interest in Ruby peaked in like ~2011 and has been on the decline, however this shows that actual usage of ruby in production has been steadily increasing year over year since then and is now second only to ASP.NET and PHP. This suggests that company adoption either doesn't perfectly track with or significantly lags behind community interest (by ~10 years), which is something I think we all know is true but this is the first time I've seen it measured in a meaningful way.
