Some reasons:
  - hard to set up
  - seldom gives correct results
  - very small parameter changes can result in extreeme and unexpected 
changes
  - large parameter changes may not change the end result at all
  - it often goes from not to almost not visible effect to overwhelming

In one of my dablings, adding "turbulence 0.01" resulted in a totaly 
white surface.
