GM's Vice Chairman Bob Lutz maintains a corporate blog at Fastlane. It's a great example of how a corporate exec is communicating with the masses outside of GM and is collecting ideas and communicating direction through a blog. It is important for corporate executives to post frequently and some may even need help with their ideas for topics, but above all it needs to be in their own words and honest.

One interesting thing to note about the GM blog is that they don't answer every customer post and Bob Lutz explains that with so many responses, it is simply impossible. For businesses considering this type of open blog, it would be a good idea to have your customer service or marketing department ready to step in and respond and communicate with cutomers if the comments begin to overwhelm the executive blogger.
