C is crap

The next time I hear some idiot say ``an array is just a pointer'' I'm going to write an OS in Haskell and remotely install it on their computer.

Any advice on selling a rewrite and/or challenges as one nears 1B daily queries for which Haskell would be uniquely advantageous?

Haskell's just really good at anything enterprise really. Frontend JS, API, traditional web backend. As long as you avoid weird/unpleasant libraries and you're proficient/comfortable in Haskell it can be a great experience. Libraries in Haskell are generally pretty opinionated so you need to make sure you know what you like. HLearn is a good example of that opinionatedness being very fecund but also unusual to people accustomed to more ordinary ML libraries. HLearn is super cool :)
