GIS and Web 2.0/ 3.0

It is new generation of internet with focus on people and social networking.

Web 3.0 - Mobile Websites, Text Campaigns and Smartphone Applications

Web 3.0 is all of the above with web experience that is no longer limited to desktop and laptop computers. It’s the Internet on the go fueled by mobile phones and tablets. Websites must be designed to be easily read on mobile devices. Group text campaigns function like e-mail newsletters in Web 1.0 which will drive traffic to your mobile website. Smartphone Applications enable content to be published and shared easily while on the go.

GeoWeb 2.0 – Consumer Mapping, Blogs, Wikis, and Social Networking sites

"If an essential part of Web 2.0 is harnessing collective intelligence, turning the web into a kind of global brain, the blogosphere is the equivalent of constant mental chatter in the forebrain, the voice we hear in all of our heads. It may not reflect the deep structure of the brain, which is often unconscious, but is instead the equivalent of conscious thought." —Tim O'Reilly

At its core, Web 2.0 is the beginning of two-way communication in Web Applications. Web 2.0 sites invite participation and that might be voting, rating, commenting and submitting new posts. So Web 2.0 sites are collaborative. For example in Social networking sites like Google, Google Maps, Earth, Bing Maps, Twitter, Facebook, Skype, Youtube can have friends, fans, followers, connections etc. So Web 2.0 category sites contains following features.

• Web 2.0 sites are Two-way.
• Web 2.0 sites are Active.
• Web 2.0 sites are Dynamic.
• Web 2.0 sites are Collaborative.

The ArcGIS Online initiative is all about the Web 2.0 style of services, sharing, and mashups.  It provides many mapping resources as well as a framework for sharing data and services.  All of this has been implemented using open standards and open Web protocol. 

Limitations

• Limit to the number of points of interest or shapes
• Tile overlays can be slow when rendered dynamically
• Interacting with vector based shapes when represented on tiles for overlay 

Web 1.0 - Websites, E-mail Newsletters

It's hard to define Web 1.0 for several reasons. So I will put it this way. What Web 1.0 really is, it's everything in between from the day World Wide Web has introduced and the day Web 2.0 has introduced. So keeping that in mind, Web 1.0 category web applications contains following features.

• Web 1.0 sites are Static.
• Web 1.0 sites aren't Interactive.
• Web 1.0 applications are Proprietary.
• Web 1.0 sites are One-way.
• Web 1.0 sites are Passive.
• Web 1.0 sites are Closed.

Web 1.0 category sites basically contain information that user's might find useful, but there's no reason for a visitor to return to the site later. An example might be a personal Web page that gives information about the site's owner, but never changes. And visitors can only visit these sites, they can't contribute to these sites. Because of this, these kind of sites are Static and they are not Interactive to the visitor which will make the site  Passive, One-way and a Closed site.
