Enterprise 2.0

So here's the question, what kinds of changes will be made in business industry as a result of Web 2.0? Are these changes primarily going to happen at the periphery or are they going to change the core of American business. It's obvious that Web 1.0 has significantly altered the nature of American business, just read Chris Anderson's The Long Tail. But the question is, will the tools of Web 2.0 alter business? If everbody is blogging at a large company everybody might have a voice. But if everybody is blogging who's going to read what's being written?

I took the ideas for these questions from Information Week. But unfortunately,I can't find the exact article that made me think of these questions.
