Just ran across Hans Mestrum’s list of employees at Google and Yahoo! who have public blogs. (Here’s a link to a downloadable PDF of Yahoo’s blogging guidelines.) From a random check, it appears only a handful identify themselves as employees of their respective companies. Ran into Google’s Biz Stone at the Business Blog Summit today in San Francisco. I think he’s cool.

Oh, and what’s the point of these employee blogs? Whether or not it’s intended, each one is a kind of emissary for his or her company. Some of these blogs are a bit too wandering and personal for my taste. Others make the blog writer look smart and plugged in. If it’s the latter, they make their employer look smart and connected.
