No one really speaks Nynorsk (or Bokmål for that matter), they write Nynorsk and speak dialects. Though it's true that if you come across a dialect that you don't understand at all, it's likely that they write Nynorsk as well. Trøndelag used to be a Nynorsk core area, by the way. Around 1940, half the population there used Nynorsk.
