Business Week Online is running a column by me, Lessons in Corporate Blogging, aimed at helping companies sort through the pros and cons of launching a blog. It draws on Dell’s and Microsoft’s recent blogospheric experiences as well as on Apple’s modestly framed blog (yes, Apple has a blog).

Also, on my essay blog, Digital Renderings, I’ve posted “Great Product, Lousy Business,” an article that examines why great technological inventions – like the supersonic jet – sometimes go nowhere in the marketplace. This is a slightly revised version of a piece that appeared originally in Strategy & Business.
