You've got Cosmo. Jay Fitzgerald's Hub Blog beat me to it (I overslept), but Boston Herald business columnist Cosmo Macero has unveiled a personal website and a weblog. No doubt Macero will make it worthwhile. But it's unusual, and a little dangerous, for a newspaper staffer to write a blog that's not connected to his newspaper's website.
Earlier this year, the Houston Chronicle fired Steve Olafson for his extracurricular blogging activities (but not before reportedly being told to "take the fucking site down"). Brit commentator Andrew Orlowski referred to Olafson's firing as an example of "America's constipated 'journalism ethics.'"
Be careful, Cosmo. It can get ugly out here in Blogland.
