Ideas about money is one example. 

People don't learn about it in schools or at home etc,, but they depend on it and are therefore very interested in it. 

If everyone else talks about the environment, corruption and high taxes, that represents a massive form of noise. 

And if I then come out and say:

"The monetary system is the most beautiful social network ever"

or 

"Inflation is and has always been a conscious policy by rulers" 

people  almost automatically tune into it, because it sticks out so much against the noise. 

Same with Bitcoin, which represents many ideas, and which actually comes true much stromger as a signal the more economic noise that is produced in the form of for bad economic policies. 

And it's the same with a bitcoiner, who may very well always transmit the  same based/low time preference signal,  but it becomes easier to receive the signal, the more society is burdened with fiat, bad economic policies and the impact these things have on non-bitcoiners.

On the other hand, if the communication channels were overcrowded with high quality ideas, adding another idea would be difficult for you to propaget from your transmitter to a high number of receivers.
