I recently listened to this podcast from IT Conversations. The podcast was delivered by Scott Anderson from HP. It was interesting to hear that HP allow staff to blog without approving their output. This must have been a massive corporate shift. The world appears to be changing and swinging away from the traditional well crafted press release and falling back to news cascading through blogs and their feeds.
The other very interesting point from this article was how corporates should, or rather should not, deal with negative comments. It was a really interesting article.
