I was looking for comparisons to Web 2.0 and the Long Tail and was happy to find this one by Joshua Porter. My comment is, "Almost, but not quite." Folks disagree on exactly what Web 2.0 means, but I like Ross Mayfield's comment best: "Web 2.0 is Made of People".
To me, the buzzwordy "Web 2.0" is about people connecting more easily, not deeper access to previously-hidden databases. It's what drives the whole nascent Word of Mouth Marketing industry. What was unavailable before was a large audience for the personal rants of someone who is not a journalist, the personal photos of someone who's not a professional, the movie reviews of someone who's not a paid critic, the videos of someone who is not a filmmaker.
It's the same concept as the fact that there is now a market for the author who is not a best-seller, or the TV show that isn't good enough for prime time... just further down the long tail.
Before, you could only show your wedding pictures to your relatives and friends. Now, the entire world can see them. And a subset of those viewers are eager to get ideas from you about your dress, flower arrangements, etc. While the captive pre-internet audience may have been bored witless, there's a quorum of internet users who are actually interested.
Porter gets back on track at the end of his post when he describes the effect of "increased choice" from the "whole catalog" of "previously unavailable" material. So true. And marketers can choose to learn how to participate in this activity, or miss out on the majority of the world's messaging opportunities.
