The real paradigm shift in Web 2.0, I believe, is the blurring the line between publication and collaboration. In the old days, people collaborated in private. They talked to their friends and colleagues, wrote letters. Later they sent emails. All the real thinking happened in those private conversations. Eventually, once the key insights had been extracted, refined, and clarified, they published: books, articles, speeches, blast memos, etc.To me, the really exciting thing that’s happening in Web 2.0 and Enterprise 2.0 is that more and more of those private “pre-publication” interactions are happening in public (or at least semi-public). I think of this as the dawn of the “Work in Progress” culture. We no longer think that something has to be finished before we let strangers into the conversation.
It will be a difficult transition for many people, since it may be harder for them to totally ‘own’ a work but the pathway that was taken will be available for others to follow; the nooks and crannies. It will be harder to end up in a dead-end when others are there to help you out. And, because of the Long Tail, there will be someone available to help.
