the option to download the current version of WordPress from WordPress.org. From there,

they can upload the source code and its dependencies to their hosting environment.

a user friendly installer have proved different.

Web 2.0

The term "Web 2.0" (2004–present) is commonly associated with web applications that facilitate interactive information sharing, interoperability, user-centered design,[1] and collaboration on

the World Wide Web.

Examples

Examples of Web 2.0 include web-based communities, hosted services, web

applications, social-networking sites, video-sharing sites, wikis, blogs, mashups, and

folksonomies.

A Web 2.0 site allows its users to interact with other users or to change website content, in contrast to non-interactive websites where users are limited to the passive viewing of

information that is provided to them.

Technology overview

Web 2.0 draws together the capabilities of client- and server-side software, content syndication

and the use of network protocols.

SLATES Search Finding information through keyword search. Links Connects information together into a meaningful

information ecosystem using the model of the Web, and provides low-barrier social tools.

Authoring The ability to create and update content leads to

the collaborative work of many rather than just a few web authors. In wikis, users may extend, undo and redo each other's work. In blogs, posts and the comments of individuals build up over time.

Tags Categorization of content by users adding "tags" -

short, usually one-word descriptions = to facilitate searching, without dependence on pre-made categories. Collections of tags created by many users within a single system may be referred to as "folksonomies" (i.e., folk taxonomies).

Extensions Software that makes the Web an application

platform as well as a document server. Signals The use of syndication technology such as RSS to

notify users of content changes.

How it works

The client-side/web browser technologies typically used in Web 2.0 development are Asynchronous JavaScript and XML (Ajax), Adobe Flash and the Adobe Flex framework, and JavaScript/Ajax frameworks such as Yahoo! UI Library, Dojo Toolkit, MooTools, and jQuery. Ajax programming uses JavaScript to upload and download new data from the web server without undergoing a full page reload.
