Despite all that, [corporate blogging obstacles] I think this is going to start happening, and the reasons are obvious. Today, in late 2004, there are exactly two companies in the world where blogging has gone wide-open: Sun and Microsoft. At both places, the impact has been overwhelmingly positive. Neither of us would consider going back for a second.
The existence of the Sun and Microsoft blogs is, every day, making our competitors' lives a little harder. This kind of competitive advantage generally just doesn't go unanswered; we are after all living in a free-enterprise system.
Most CEOs, and all good CEOs, are very outward-facing. They see what's going on, and they don't sit tight and let competitors maintain a competitive advantage. Especially when setting up enterprise blogging is easy and cheap.
