An interesting piece on Walt Mossberg. Final paragraph sums it up well:
What differentiates Mossberg from most bloggers, according to Marissa Mayer, a Google vice-president who focusses in particular on the experience of consumers, is that what he writes “is all based on his use of the product”—he’s not racing to be first.
Her colleague Eric Schmidt suggests that, while the Internet may yield enormous amounts of information, it is easy to drown in it. So consumers, Schmidt says, “go to brands they trust.” He adds, “Walt is a brand.”
