It depends. Stuff like Time magazine and mainstream corporate media in general I’m going to speed read it because after decades of study and learning from sites like fair.org I’ve learned they tend to be full of shit with many half-truths and typically only telling part of the story that fits their corporate owner’s agendas. On the other hand, I tend to slow down and read alternative news sites very throughly.
