Donald Bruce Stewart recently published an in-depth analysis of Hackage's download statistics that shows many interesting characteristics:
- All of the 1,200 Haskell softwares on Hackage combined have been downloaded as many times in total as a single OCaml program, MLDonkey, from Sourceforge (let alone OCaml's other popular software like FFTW and Unison).
- Over half of the packages on Hackage have been downloaded under 300 times.
- Dependencies are multiply counted so these figures are a substantial over estimate.
This confirms our suspicions that the few lines of real-world Haskell software ever written have been tested by only a handful of people. Perhaps Haskell will become more mainstream in the future but it seems to be quite a long way off today.
