Web 2.0 Introduction

Web 2.0 is the network as platform, spanning all connected devices; Web 2.0 applications are those that make the most of the intrinsic advantages of that platform: delivering software as a continually-updated service that gets better the more people use it, consuming and remixing data from multiple sources, including individual users, while providing their own data and services in a form that allows remixing by others, creating network effects through an "architecture of participation," and going beyond the page metaphor of Web 1.0 to deliver rich user experiences.

Participatory and collaborative: In action

Wikis:
Used where they make sense, wikis can be a powerful source of information for an organization about their visitors, as well as a powerful tool for the visitor to be successful in their task on at a site.

Barometers:
Comment on this page, rate this product/service, tell-a-friend, etc.
Comment on this page:
Provide “free-form” textual comments/suggestions about selected pages or applications on the site.
Enables the end-user to influence what we present on our pages or determine how our applications should/could work

Ratings: collect ratings and use them to influence navigation by featuring articles with good ratings on homepages or showing ratings on the page (1-5 Stars)

    • Distributed Personalization: enabled through identity services
    • Dynamic Related Links, Syndicated Search (OpenSearch RSS)

• Shipping status (DHL, UPS, FedEx…)

Rich Internet Application: In action

Using the Technology :

Flash
Flash technology has become a popular method for adding animation and interactivity to web pages.
Improving the Graphical aspect of the web application.

AJAX
Asynchronous JavaScript and XML, is a web development technique for creating interactive web applications. The intent is to make web pages feel more responsive by exchanging small amounts of data with the server behind the scenes, so that the entire web page does not have to be reloaded each time the user requests a change. This is meant to increase the web page's interactivity, speed, and usability.
Far Richer experience (with AJAX Drag and Drop).

Joy of use: In Action

• WebCams and VoIP
The ability to click a link on the website which opens a dialogue with a live person over the web (either voice or voice and visual)

• Product Viewing and Assistance
Servers: 360o view to show you how to set up and configure a product

• RSS aggregation
Give visitors the ability to view all of their RSS feeds in one place

Mobility in the Web 2.0 world: In action

• Enhance existing functions to be accessible from the wireless devices
Drive traffic to the mobile version of the applications through awareness and auto redirects
Provide fast access through Search to a wide variety of content from any device
Short URLs and easy navigation very important

• Use 2D barcodes in advertising and direct marketing materials to drive Web traffic
Customers who see an ad in a magazine or on a billboard, or receive direct marketing
material, can point their mobile phone to the 2D barcode and access the related Web site
directly without typing lengthy URL addresses

• Provide more syndicated content for site visitors
Allow the visitors to take away pieces of your content and explore them at a time of their own choosing (audio or video podcasts, RSS feeds, etc.)

• Automatic Alerts to the cell phone to notify the client of key events:
Their order has shipped
A proposal is ready for their review
Payment has been received
