Sadly, this happens all the time, and both ways, without any announcement. Obviously, Mahalo is experimenting with their pricing system, like they have been doing before also. They shortly increasing the price from 0.25 to .50, and now back again.
I think we'll see some more price changes in the near future. (hopefully not downwards...).
It seems that the price of the answers fluctuated over time. See @buddawiggi answer to this mahalo.com/answers/mahalo-answers-commun... Only 3 days passed with .50 cents questions.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
