i never knew git annex was Haskell actually! maybe this is a marketing failure. I'd love to contribute. Haskell projects are trivial to contribute to compared to all other languages (speaking as a Haskeller)

I see this take often with HNers. Have you considered that the author just likes a Haskell? That it's fun? And that without it, they wouldn't have bothered spending the time on the project period?
[1] I learned enough Haskell to contribute to your average codebase as an undergrad at a state school who never learned a higher level language than C in school. Neither talent nor experience are needed. But maybe they're detriments given the interplay with ego.
