A good article on this topic – in English
Following the introduction of blueKiwi I made recently, I would like to share with you a fantastic article written with one of the most influential blogger in france. The guy is involved in web2-stuff questions and he is one of the leading specialist for Second Life.
Once again, these concepts of "2.0" remain unclear and are often criticized. However, there is something happening and, yes, as it is difficult to find the adapted vocabulary, Enterprise 2.0 will be fine for the moment.
He wrote a remarkable article in French dedicated to the Enterprise 2.0 topic.
Then he decided to translate it in English.
Extract :

If “Web 2.0” was 2006’s buzzword, we begin to hear much of Enterprise 2.0. To make a long story short, it means using inside an enterprise the successful tools of web 2.0.
Please, do not sum-up this to internal blogs or wikis, this notion
gather much richer fields and above all implies deep mutations which go
farther than rolling-out new tools.
Before going through my overview map (which can confuse you), I’d like first to introduce the subject.
