And it will be for these reasons in no particular order:
1. They think it is about technology.
2. They aren't prepared to deal with the friction that allowing their staff to connect generates.
3. They will assimilate it into business as usual.
4. They will try to do it in a way that "maximizes business effectiveness" without realizing that it calls for a radical shift in what is seen as effective.
5. They will grind down their early adopters until they give up.
6. They will get fleeced by the IT industry for over engineered, under delivering solutions, think that Enterprise 2.0 failed to live up to its promise and move on to the next fad.
7. Lack of patience
8. It is not companies who do Enterprise 2.0 it is individuals.
A serious point about levity.
A word or two on love
Don't just do something stand there
Why it is the "social" in "social computing" that matters
My favourite Drucker quote ...
The perils of making things easy
We get the world we deserve
Is it just technology?
Are we mad?
