Web 2.0 is one of those buzzwords that is tossed around a lot but rarely defined, almost as if you're expected to intuitively know what it means without needing a formal explanation. Yet, it probably means a lot of things to a lot of different people, and it has no doubt changed some of its meaning along the way.
From a broad conceptual standpoint, I look at the beginning of the Web 2.0 era as when the Internet became "self-aware" and started to take advantage of its unique characteristics as a medium unlike anything before. The key focus became not in finding new ways to "create" content but rather new ways to "consume" content. This manifested itself through an emphasis on website interactivity and user contributions. An important realization was that the Internet's greatest asset was not the new communication tools it introduced, but rather the fact that the average person now had access to these same communication tools that had normally been reserved for a select few media professionals. Websites like YouTube, Facebook and Wikipedia, which rely heavily on user-generated content, established themselves as relevant social forces. Social networking took off, and people began to create an entirely new "online" persona for themselves that seemed to exist independently from their actual self. Basically, Web 2.0 replaced passive participation of online content with active participation.
In his
prescient blog on the issue, Tim O'Reilly mapped out what he saw as 8 defining characteristics of Web 2.0. One of the characteristics he mentions is "Harnessing Collective Intelligence." As he explained, "Hyperlinking is the foundation of the web. As users add new content, and new sites, it is bound in to the structure of the web by other users discovering the content and linking to it." Taking a look at the site
Metacritic.com, we can see this aspect of Web 2.0 in action.
Metacritic is a collection of critical reviews about various forms of entertainment media, such as movies, music, TV and videogames. The site provides direct links to the original reviews and also formulates a "Metascore" based on the average review. This Metascore is a great way for the user to instantly get a sense of the general critical consensus, without having to search for all the information themselves. This is illustrated in this page for a new album by the band The Flaming Lips:
As you can see, the Metascore is prominently displayed, with a corresponding description of "Universal Acclaim" to further summarize the information and make it easily digestible for the user. All of the relevant album information is listed, along with a short summary. For those who want to read the actual reviews themselves, a short excerpt is provided on the page with a link to the full article:
Along with these formal reviews, there is also room for audience input and interaction. A separate User Score is listed underneath the Metascore, and user-submitted reviews are displayed along the sides and bottom of the website. There is also an area for discussion forums on the separate entertainment topics. Here we see an example of the User Reviews displayed on the right alongside the other, more formal content:
This audience participation and user-submitted content is a key feature of Web 2.0 and reflects the sense of the Web as an online community and social portal. According to
Daniel Nations of About.com, "Metacritic has all you want in Web 2.0 site with both user reviews and expert reviews from around the web."
Like many Web 2.0 websites, Metacritic doesn't actually create its own content but rather organizes and presents it in a simple, user-friendly fashion. It builds upon the infrastructure of information that was available in the old media days and provides a service that is unique to the Internet age. As stated by Metacritic co-founder Marc Doyle in
this interview:
"
Before the rise of the world wide web, consumers were at the mercy of their local critics for advice about which movies to see, what games to buy, etc. Furthermore, the influence of advertising campaigns and the emphasis on fawning quotations from obscure critics that nobody had ever heard of in newspaper/magazine ads was huge. Bad movies and games could be thrust on consumers without a great deal of education to rebut the messages from PR companies or the potential biases of individual critics. Metacritic's mission is to bring together the most professional, skilled and respected critics in each section of our site (movies, games, music, and TV) to provide our users with the most reliable indicators of quality upon which they can base their purchasing decisions. Again, this type of service would not have been possible before the web was developed." (Emphasis added)
This quote perfectly articulates one of the key aspects of Web 2.0--the opening of and democratization of media, so that it is no longer only in the hands of a select few. This is an extraordinarily powerful development that has had a profound effect on our culture and society. Metacritic serves as a great example of this collective sharing of information and intelligence that has permeated the Web 2.0 era.
It is also interesting to note that there is growing talk of a Web 3.0 and speculation as to what that might entail. However,
as O'Reilly points out, Web 2.0 came about as a result of the dot-com bust, so for there to be a Web 3.0 there would need to be a "serious discontinuity from the previous generation of technology." Even so, some of the ideas as to what Web 3.0 will be include "web without browser" and "the breaking of the screen/keyboard paradigm." These are certainly interesting and exciting concepts, but no matter what the next generation of the Web experience turns out to be, it will no doubt be heavily powered by the collective force of the end user.
