Defining Web 2.0
- 1. Defining Web 2.0 There is a lot of disagreement about what the phrase Web 2.0 means. Let‟s clear that up. One answer is that Web 2.0 refers to the propensity of recent Internet applications to be more collaborative and provide for a richer user experience. Web1.0 was a Web site that looked like a brochure or a resume. Web 2.0 is a blog. Web1.0 was your newspaper‟s classified ads, just webified. Web 2.0 is eBay or craigslist. Web1.0 was Netscape (i.e. here‟s some software). Web 2.0 is Google (there‟s nothing to install but it‟s powerful). Web 2.0 is about harnessing collective intelligence and eliminating the software release cycle – it‟s about providing services, not products. It‟s about trusting users as co-developers of content or even of technology. As an example, Amazon.com does this with its user review system. A more cynical definition of Web 2.0, found in the blogosphere in Europe, (where they tend to be more conservative about technology) is „Bubble2.0‟. What they mean by this is that some marketers have gone off of the deep end applying this term to anything. And they‟re right. Europeans are always right (just ask them). Bubble1.0, of course, burst in March of 2000 when the NASDAQ reached 5,000 points (it‟s 2,200 today). Some companies emerged successfully from that bubble and some did not. Bubble2.0 will probably be smaller but will have some winners and losers, too. Web 2.0 includes a social dimension, greater openness and transparency in process. It includes the use of new technologies, such as Really Simple Syndication (RSS), Web Service Definition Language (WSDL) and eXtensible Markup Language (XML). It has a more open style and a "keep it simple" approach. Many of these attributes go hand in hand. For example, open-source technologies tend to be simple, transparent and lightweight. It‟s more of an attitude than a specific architectural protocol. Web 2.0 has:
- 2. New technologies, like XML, Simple Object Access Protocol (SOAP), WSDL and RSS. Collaboration and content repurposing, like Sourceforge.net or Youtube.com. Different business models with longer „tails‟ like Google Adwords as opposed to DoubleClick. The Wikipedia is a great example of a Web 2.0 application, as are mashups like Rememberthemilk.com. (Mashup is defined as a Web site or web application that combines content from more than one source.) “On demand” offerings from companies like Journyx and Salesforce.com fit into the new paradigm, as well. With Web 2.0, groups of users within companies control their own destinies by shared administration responsibilities more than was the case in previous software models. New Technologies Web oriented architectures based on XML, SOAP and WSDL make mashups possible. Rememberthemilk.com is a Web site that combines Google mapping technology with your personal task list, allowing you to see on the map where your tasks are located in the real world. You can see what's nearby or on your way, and plan the best way to get things done. IBM‟s answer to XML is Representational State Transfer (REST) which exposes elements of an application via the software- as-a-service (SaaS) model. Journyx Timesheet‟s WSDL API enables similar mashups to occur with its SaaS site. And Salesforce.com‟s AppExchange push is based on the mashup concept as well and heavily dependent on XML as the application programming interface (API) mechanism. IBM is another vendor that is shifting its innovation strategies towards enabling a broader web environment as opposed to just adding new features to existing applications like IBM‟s Lotus Notes middleware tool. To this end, they‟re working on technologies like dogear (similar to http://del.icio.us) and Feedme (an RSS based improvement to the old IBM Tivoli Enterprise Console product). Technologies that allow a richer user experience in the browser as is displayed in Google Mail and Maps are also considered to be part of the Web 2.0 movement.
- 3. Communities Youtube (video sharing), Digg (IT news voting) and Wikipedia (way better than www.britannica.com) exemplify the community aspect of Web 2.0 thinking. The content comes from users, not authorities, and it‟s amazingly high quality. One of the greatest communities on the Internet is Sourceforge.net where Python, Perl, Apache, PostgreSQL and thousands of other great technologies were developed. The company that owns this site, Va Software (Nasdaq:LNUX), realized that the collaborative project-oriented atmosphere created on Sourceforge.net would also be useful for large IT shops like those at FedEx if they added some security features and issue tracking. Sourceforge Enterprise was born, which allows companies to securely pull external software developers into their development process – whether they‟re from partners, customers, or the public at large. For an example of how Web 2.0 is impacting governments, compare sites like DavisWiki.org to a traditional city Web site. Older firms, like EBay or Amazon, are arguably successful precisely because of the more collaborative nature of their Web sites. Amazon lets you vote on books and then vote on other peoples‟ votes. EBay has buyer and seller rankings based on feedback. And content is king in both cases. In fact, Amazon lets publishers (even small ones) include content relevant to their book in the listing for the book. The ownership of this information becomes questionable once uploaded. See how Amazon wins? New Business Models New business models based on advertising, subscription, usage or revenue sharing will crop up that will feel very different than traditional technology licensing. Web 2.0 is a shift -- a shift away from closed, inflexible, proprietary models to a more collaborative, participatory, open model for content. It‟s a shift towards a world where we are all authors, videographers, programmers and contributors. Companies that enable that will win and those that don‟t will lose. It‟s as simple as that.
