The r/programming study question about "used languages in the previous 12 months" can
be investigated together with the 50 most popular programming languages
described by TIOBE (in November 2011).
The figure below shows the degree of correspondence in terms of rank order correlation. For TIOBE's top 50 languages, the correlation was .57 whereas it was slightly higher for the top 25 languages of TIOBE (.62).
The correlations are based on the table below, which has been compiled somewhat hastily. Observations with tied ranks use the mean rank of the tied observations. More detailed analysis about program language use in the survey can be found here and here.
