"First, it is important for any company to understand and participate in such an important market trend, something made easier if you have your own people actively involved in the blogosphere; and second we believe that IBM's open attitude toward blogging helps us attract and retain top talent." (from Irving Wladawsky-Berger's blog - Irving is the Vice President, Technical Strategy and Innovation at IBM)
