I disagree (again). If you are a technology focused startup, chances are you are looking for highly talented people for your core team. You usually don't want the average PHP or Java Joe; you want more! And those you are looking for are usually not afraid to learn learn yet another language, if they don't already know. On the other hand if you are not building a technology focused startup, but simply need some software as a vehicle to drive the main business, you are right to look at the cost-benefit analysis and choose a more mainstream language, for which you can find cheap and easily replaceable labor in your area. I'm not saying you can't get the job done in a mainstream language; but I postulate that the mindset and attitude towards code of a good Haskell or Scala programmer is vastly different from your less expensive PHP or Java programmers. Some want to push the limits of what's technologically possible and others just want their paycheck by the end of the month; they are in both camps; are they evenly distributed?
