No, Daniel's suggestions do apply because you want to generalize 
boundaries. If an area is defined by many short boundaries, there is 
nothing to smooth because each boundary is processed separately and you 
need to build polylines first in order to get nice results. See previous 
posts on this topic.

Also type=boundary instead of type=area would help.
