I don´t know if the time of elaboration is really representative here. I sometimes struggle writing only one good sentence and then on another day I could right a book in only one day. But I am totally with you that the 'efforts' paid by the author should be rewarded fairly. That means that these efforts have to be appreciable - e.g. by an innovative idea, creative structur of the post, outstanding presentation of pictures,.... the list could be endless.

Time is not only measurable in time. That sounds weird :-) But time here is measured with the currency attention. That means that time has only a value in combination with an action towards something or somebody. I could open an article, close my eyes and don´t do anything at all. But that´s neither quality time nor real attention. I don´t think I should get paid for that.
