I rebuffed one of his detractors earlier today and couldn't agree more. He DOES ALWAYS give credit to the source material.
Also, and ironically, he is doing a great curation service for Steemians, by choosing the content he does. I in fact appreciate the cull -- although i wind up reading almost everything on Zh anyways...
I say pick your battles, and kearn from the people who are doing it right, if a little less imaginative.
