An email exchange with the editor of MIT's Technology Review has improved my understanding of the magazine's new approach.

It will "explain [emerging technologies'] market potential and possible financing, otherwise it’s just hyperbole and gee-whizzery." But it will not cover markets and financing for established technologies.

This shifts my view by, like, 180 degrees, because in fact most business mags don't do a very good job covering the financial and business dimensions of new technologies, so there is an interesting niche to be filled.
