this is pretty rich considering that Sun had a piece of pioneering corporate blogging as marketing activity supported from the top. Unfortunately, that happened to be a complete former McKinsey consulting dork named . . . . look it up the history of the last years of Sun if you don't know.
I had a Sun blog. It wasn't much, but before the platform really took off, mine was in the top 10 or 20 regularly. There was always good, and sometimes difficult, discussion on the blogging alias about whether the bloggers should control the content or if the marketing dept. should. If you were part of that time and community, you know what I am talking about.
Then Oracle came in with their controlling ways, and having an oracle blog was a nightmare of rules and regulations, and you could not resist. Or discuss. At that point it was clear that the marketing dept. won.
