[edit] The Network Effect

Network effects become significant after a certain subscription percentage has been achieved, called critical mass. At the critical mass point, the value obtained from the good or service is greater than or equal to the price paid for the good or service. As the value of the good is determined by the user base, this implies that after a certain number of people have subscribed to the service or purchased the good, additional people will subscribe to the service or purchase the good due to the positive utility:price ratio.

A key business concern must then be how to attract users prior to reaching critical mass. One way is to rely on extrinsic motivation, such as a payment, a fee waiver, or a request for friends to sign up. A more natural strategy is to build a system that has enough value without network effects, at least to early adopters. Then, as the number of users increases, the system becomes even more valuable and is able to attract a wider user base. Joshua Schachter has explained that he built Del.icio.us along these lines - he built an online system where he could keep bookmarks for himself, such that even if no other user joined, it would still be valuable to him. It was relatively easy to build up a user base from zero because early adopters found enough value in the system outside of the network aspects. The same could be said for many other successful websites which derive value from network effects, e.g. Flickr, MySpace.

[edit] Harnessing Collective Intelligence

A collective intelligence is achieved when a critical mass of participation is reached within a site or system, allowing the participants to act as a filter for what is valuable. The user reviews on Amazon.com sort out the worthy resources from the inadequate.

[edit] User-Produced Content

Web 2.0 emphasizes the ownership and creation of user-produced data or content within a system. The next generation of Web developers realize that it is the auction listings that make EBay so successful, the user reviews that are the unique value of Amazon.com. Their goal is to design applications which are conducive to and will naturally generate this type of original content. Encouraging that participation is vital to Web 2.0 companies because the more people who contribute, the better the network effect and the collective intelligence. Ellyssa Kroski


  • Capturing the information from Google Scholar on relavent articles through collective bookmarking and tagging.

[edit] Perpetual Beta

This characteristic of Web 2.0 is also referred to as the “perpetual beta” because the application is constantly being monitored and tested for usability and improved accordingly. There is never a “finished” version or product. Ellyssa Kroski


[edit] Less is more

The philosophy behind developing for Web 2.0 is “less is more”. Its objectives are simplicity and efficiency. Ellyssa Kroski

  • Mashup

[edit] Syndication

Sharing, not controlling is paramount to the new Web. Authoring information in a structured format which can be used and re-used is crucial for Web 2.0. It is part of the “some rights reserved” model of creating and distributing information. It is a model in which you control your data to the edge of your system and then you let it go. Ellyssa Kroski

[edit] Reusability

The combination of two or more individual Web applications to create a new one is called a Mashup. The best known mashup to-date is Housingmaps.com. It is a combination of real estate listings from Craigslist.com with Google Maps which allows house and apartment hunters to easily locate real estate listings. The ProgrammableWeb has a mashup database listing hundreds of such Web 2.0 applications.Ellyssa Kroski
