When you visit a new country, a good way of getting started is to begin with a tour that gives you
a first idea of what the country looks like and the key sites that you’ll want to visit in more detail.
This chapter is the tour that will give you the first idea of what a Web 2.0 application looks like
from the inside and help you to get the big picture.
a first idea of what the country looks like and the key sites that you’ll want to visit in more detail.
This chapter is the tour that will give you the first idea of what a Web 2.0 application looks like
from the inside and help you to get the big picture.
The Web 2.0 world is wide and rich, and the typical “Hello World” application wouldn’t be
enough to give you a good overview of a Web 2.0 application. BuzzWatch, the sample Web 2.0
application that you’ll visit in this chapter, is thus more than the typical “Hello World” program-
ming example. This chapter introduces most of the techniques that you will learn throughout the
book, and you might find it difficult to grasp all the details the first time you read it. You can see it
as the picture that is on the box of a jigsaw puzzle and use it as a guide to position the different
pieces that you’ll find in each chapter of the book. You can glance through it rapidly at first with-
out installing the application, and revisit each point after you’ve seen the details in the corre-
sponding chapter.

Introducing BuzzWatch
The application that you’ll explore in this chapter is a program that aggregates information from
multiple sources to give a different perspective. This kind of application is called a mashup and
you’ll see how to create mashups in more details in Chapter 15. This program is for executives
who want to see, side by side, financial information about a company together with the vision
from the web community on this same company. The goal is to compare the images from a com-
pany in the financial community (illustrated by information available on Yahoo! Finance) and in
the web community (illustrated by del.icio.us). There are a number of sites that let you build pages
with information pulled from different sources, but this one is really simple: you just need to enter
a stock symbol and a del.icio.us tag and you’re done. To share it, you’ll also be able to save these
multiple sources to give a different perspective. This kind of application is called a mashup and
