Sadly, this article was several minutes of my life that I don't think I'm getting back.  It's 8 pages long so it's hard to come up with a quote.  Instead I'm going to substitute in a very snarky summary...

Web 2.0 is great and if you just embrace all these buzz word laden approaches bottom up management techniques it will revolutionize your company.  Just look at all these people trying to make themselves look good people we interviewed who have embraced it and made it look like they accomplished something in their year end review had great success.  So empower your employees and switch to a more bottom up approach and all will be good and right in the world as you bask in the glorious glow that is Web 2.0

As you can probably tell from the above summary I don't think the conclusions here hold any weight whatsoever because they are based on evidence that is almost certainly false. 

The content of this article is based on interviews with corporate officials and as anyone who has participated in these types of interviews will tell you they are almost always full of lies.  Of course the CIO who endorsed blogging because he read about it in Fortune is going to say it succeeded in his corporation.  What else would he say?  Of course the CEO is going to say he's constantly looking for ways to engage his staff.  Have you ever met a boss that said "I don't value the opinion of those under me"? 

But here's the thing, there's "what we say in an interview" and then there's reality.  Everyone says they value the opinions of their employees but very few executives actually do. 

This is something that anyone who has ever worked in corporate America or read a Dilbert comic for that matter knows.

I worked as a consultant, I know what ACTUALLY goes on in these companies and the stuff they say in interviews isn't even close. So now lets look at the reality of 99% of corporate environments and why it works against adoption of Web 2.0 principles.

Upper Level Management gets paid a lot.  They justify that large paycheck by doing everything in their power to make themselves look indispensable.  Being indispensable means making it look as if all or most of the good ideas are coming from you. 

That, right there, is why Web 2.0 doesn't work in the corporation.    You can't embrace a collaborative process AND make yourself look like the indispensable oracle of all good ideas.

If you want to implement these technologies you have to approach it by finding ways to get around that limitation.  You have to look honestly at the social structures that already exist and work within those social structures to achieve results.  Here's an example:

Open Wikis in corporate environments don't work.  Because the Senior VP of Marketing doesn't want the CEO to know the company's next big marketing push came from the guy three levels below him.  You see he's afraid the CEO might give his job to that lower level guy and that's not really acceptable in his eyes. 

So you have to accept that limitation and implement what you can.  Maybe have a private Wiki in each department that can't be viewed from the outside or an anonymous Wiki that prevents anyone from seeing where the good ideas come from.  Or any of a thousand other solutions. 

The above quoted article contains absolutely no pragmatic solutions to get around these various issues and that is exactly why it's next to useless.
