because there is only so much time that can be spent consuming it. This is the problem with the attention economy, because we only have so much attention to spend...
The sad thing is, even good books are getting extremely hard to pay some attention to. Especially because of the slower pace of consumption and the requirement to be fully focused on reading. And I used to love to read books. I still do but I can hardly make ( consume) five to ten in a year :(
