Web 2.0 @Work
I reckon the companies themselves are to blame. Social networking is time consuming but can be extremely useful. The problem is, most companies don't like to share information across departments, let alone invite collaboration on ideas from the outside world.
Silicon Valley dorks will pretend as if wikis and blogging are somehow going to make companies smarter. Usually, they end up helping competitors and journalists.
So, yes, Web 2.0 doesn't work at work very well. Not yet. And the companies are to blame, but only because they're doing their jobs and trying to stay competitive.
