That's life folks. Some people just need to build products and get them to market for paying salaries and supporting their family. If you ask me what is bad about Haskell, it is the difficulty in finding developers and difficulty on making other developers to work with apps written in Haskell.
I don't program in Haskell, I have people doing the programming side (don't get me wrong, I wrote 100k LOC in Java over the 12 months) and if I ask other developers around here to learn Haskell, it is difficult to get any enthusiasm.
