| The main problem is the difficulty to hire Haskell programmers. Recruiting is crucial to a startup's success. "We were pleased to get a total of 42 applications, of which 19 merited serious consideration, and we eventually settled on a shortlist of 7 to interview. " [0] Then there's the entire ecosystem surrounding Haskell, which is still old and antiquated (looking at you Cabal) and moving very slowly (interfacing to NoSQL or AWS, etc...). > looking at you cabal See this link for a solution: https://news.ycombinator.com/item?id=9766943 > interfacing to NoSQL I recently used the Haskell riak[3] binding in my day job for an application. The mongoDB[4] package was uploaded "Tue Jan 19 06:04:06 UTC 2010"[5] > AWS There has been an AWS binding since 2011[1][2]. > etc cassandra[6][7][8] couchdb[9] > Finally, the very high bar to just learn how to correctly program in Haskell puts it out of reach of 99% of the developer community. A 10 year old can do it[9], so I'm sure more than 5% of the developer community can as well! I wouldn't say I'm a spectacular programmer and I have both learned Haskell and used it in the real world easily enough. I will admit in the past there was a learning issue, but actions to make Haskell easier to learn have (and continue) to happen.[11][12][13][14] I'm looking forward to any rebuttals you may have to these! :) 0: http://www.well-typed.com/blog/2010/08/on-hiring-haskell-peo... 1: http://hackage.haskell.org/package/aws-0.0.1 2: http://hackage.haskell.org/package/aws 3: http://hackage.haskell.org/package/riak 4: http://hackage.haskell.org/package/mongoDB 5: http://hackage.haskell.org/package/mongoDB-0.1 6: http://hackage.haskell.org/package/cassandra-thrift 7: http://hackage.haskell.org/package/hscassandra 8: http://hackage.haskell.org/package/cassy 9: http://hackage.haskell.org/packages/search?terms=couchdb 10: https://superginbaby.wordpress.com/2015/04/08/teaching-haske... 11: https://github.com/bitemyapp/learnhaskell 12: http://haskellbook.com/ 13: http://www.amazon.com/Beginning-Haskell-A-Project-Based-Appr... 14: https://en.m.wikibooks.org/wiki/Haskell |
