Incentives also tend to disfavor "popular" work like blogging, but I think in parts of academia that is somewhat changing. May be changing less slowly with regard to experts in industry, some of whom also have confidentiality issues to worry about. As one example, law-professor blogs have really taken off. They're good for building reputation and making a legal argument actually have real-world impact (people read them, whereas the average law review article is little read), and sometimes have even been cited in court decisions! So there is a movement towards law professors doing more popularly oriented, but still legally sound, writing; and towards universities taking this into account. Science has also long had some research/popular-writing crossover, and there are a number of researchers who blog in areas like physics and climate science. And mathematics has an increasingly strong blogging culture, with Terence Tao setting the nearly impossible to top example. So I think there is good stuff out there if you know where to look. Of course, it's also good to experiment on your own, and also to look elsewhere (e.g., in books).
