What is Web 2.0?

Frankly I haven't known about this before I joined my school. As soon as I heard this web 2.0, I was as keen as mustard about this. :D And also think how about web 1.0? I don't know even though web 1.0. :D he he

When I read and learn from the resources, I know about that. I would like to share a short note rather than long cuz it can save the time.

Web 2.0 is Technologies such as social tagging, blogs, wiki,social networking, mashup and etc.

Characteristic of web 2.0 are as follows.
.Web as a platform - foucs on service and content like Google, blogger because users can control the entire web as a platform.
.Lightweight programming models - SOAP webservice like Google Web API and RESTFul to allow the creation of API in the form of URL like Yahoo developer network
.Reusable sources of information - It's so clear like google API or Youtube API that you can reuse in your application
.Harnessing collective intelligence - That means there is medium for interaction and participation to form a new new interaction such as flickr & del.icio.us, google map. Early web form connect the different web sites by using hyperlik but web 2.0 like blogger you can connect other sites by using medium interaction.
.Richer user experience - In this web 2.0, more richer experiences for user to interact with the system by using AJAX such as Google MAP. You feel more interact with the system's action by browsing the map in the google.

It's an amazing technology which can make more easir to make API as your own, your template and design, and it's also more interactive.
