Back in June, Ken Makovsky and I did a podcast on the subject of business blogging. For our second show in this series, we decided to get the perspective of someone who heads up a successful corporate blogging initiative. So, we looked no further than GM, which publishes several very well-known and respected blogs. Bill Betts, GM’s Communications Web Services Manager, spoke with us recently about the role of blogging at GM and what the corporate communications team is doing to make it a success.
