Working grad student scientist here. One reason is prestige. This is not a fluffy concept in academia - publishing in prestigious journals means funding and tenure for professors and good job prospects for grad students. Another is time. Every minute spent blogging is a minute spent not doing the above. Another is curation. Frankly, Nature, Cell, Science feature work from the biggest, most well-funded labs. They have a lot of stuff masquerading as novel, but they also feature pioneering, transformative work. Science is about methods, and the fancy journals are where you see methods first. Its a tragedy of the commons situation, sort of. We are all very aware of the problems with academic publishing.
