Enterprise 1.0 vs. Enterprise 2.0

From The Software Abstractions Blog..
What exactly is "Enterprise 2.0"? The main themes that are emerging, seem to be products/technologies that:

1. facilitate better communication
2. harness collective intelligence and innovation
3. enable user-generated applications (enterprise mashups !)

The communication aspects present the most powerful paradigm-shift.
