The next big thing that is making waves after the World Wide Web is the so-called Web2.0.

Web 2.0 defines a newer incarnation of the World Wide Web typified by the transition from the typical website hosting HTML/XHTML pages, to a platform that provides a point of presence (sometimes known as a Web portal), from which any of the following interactions may occur.

Web 2.0 is the philosophy of mutually maximizing collective intelligence and benefit for each participant by formalized and dynamic information sharing and creation.

"Web 2.0 is a trend in World Wide Web technology, and web design, a second generation of web-based communities and hosted services such as social-networking sites, wikis, blogs, and folksonomies, which aim to facilitate creative information sharing, collaboration, and sharing among users." When we talk about Web 2.0, we cannot stop discussing about the way people have welcomed its entry.

With the entry of Web 2.0, there is no doubt that the dimension of business on the internet has changed completely and people have started using the technology to their convenience.

There are many people who eat, drink and sleep on the internet but still not aware of the uses of Web 2.0 and the various Web 2.0 sites.

The first Web2.0 conference that held in 2004 was considered the giant step towards making the Web 2.0 popular. This Web 2.0 conference was in a way the pioneer for many such conferences that followed.

According to our experts there are lots of companies or products that embody these principles in their description of Web 2.0-ness.There are four levels of Web 2.0 applications. To start withLevel-3 applications, the most "Web 2.0 Application"-oriented, only exist on the Internet, deriving their effectiveness from the inter-human connections and from the network effects that it makes possible, and growing in effectiveness in proportion as people make more use of them. Some of the Web 2.0 sites that fall in this category are eBay, Craig list, Wikipedia, del.icio.us, Skype, dodge ball and Ad Sense.

When we talk about Level-2 applications that support Web 2.0, we mean those Web2.0 applications that can operate offline but gain advantages from going online. Flickr is one such Web2.0 site, which benefits from its shared photo-database and from its community-generated tag, database. Next comes Level-1 applications that operate offline but gain features online.

Writely (now Google Docs & Spreadsheets) and iTunes (because of its music-store portion). Level-0 applications work well in offline as well as in online. Map, Yahoo! Local and Google Maps (mapping-applications using contributions from users to advantage can rank as "level 2"). Non-web applications like email, instant-messaging clients and the telephone fall outside the above hierarchy.

When we talk about Web 2.0 Technologies, Web 2.0 tend to foster innovation in the assembly of systems and sites composed by pulling together features from distributed, independent developers (a kind of "open source" development and an end to the software-adoption cycle, the so-called "perpetual beta"). Web 2.0 technology encourages lightweight business models enabled by syndication of content and of service and by ease of picking-up by early adopters.

Web 2.0 marketing is nothing but getting the best out of marketing on the web. Some of the most common Web 2.0 strategies include social Book-marking, RSS marketing, video marketing and Blogging. It involves getting repeated viewers to one web site and this can only be done if we provide the users with quality content.
