What does "properly" mean in this context? All of my income is from my own software businesses. I used to try to do this with Ruby, and there were lots of problems. Now I do it with Haskell, and there are fewer problems. This ended up being a very good business decision for me. What is the return on investment for me as a businessman on bothering to "do anything properly" when the resulting product is both cheaper to write and is more stable if I just use a better tool? What do I actually gain? Some kind of nerd-honour?
