web 2.0 in intranets

I have found a very interesting video on youtube. It is about the current trend in the corporate intranet, the introduction of web 2.0 thinking.
How will IT and communication people convince the management about the need of change? Good question. I think, step by step.. Old managers go, new come.
The talk is full of todays buzz-words: rss, wiki, blog or podcast.
It is very interesting that which industries are heading this way: banking and health care. They need fast communication and fast data or knowledge exchange. And not least they are working with high security information!
Watch the video, it is interesting.
