A quick overview to Web 2.0

1 Netflix
This is really a web 2.0 page. First of all, everything is dynamic. The page load the movies you like as you describe in your own profile. The subscription process is very easy and fast. You can rate the movies at real time, share everything with your netflix-friends in just a second. Furthermore, the web design is very simple, you do not get distracted with annoying details. I chose it because I'm subscribed right now and I'm very satisfied. I have used for more than 2 years and noticed that it have been in continuous improvement.

2 Kayak
It is a webpage to calculate flight/hotel/rental rates for travels. It has a single interface at the welcome page because it shows just the fields you need to fill to start searching. It also uses the predictor feature when entering city names. Then it shows all the results in a interface where you can filter very quickly by clicking on small images, and you don't have to wait to the page to be reloaded for each filter selected. At the end, it opens others travel rating pages for you with the same information previously entered to compare all options available in the web. I like it. I chose to check it from the TIme magazine list because it could be very useful when planing travels.

3 Twitter
Since this site is based in social network, it is Web 2.0. I chose because I have heard a lot about that, yet I hadn't tried. The webpage consists on following news from specific areas of interest. I think is a good idea to share information in this way. I gave a try. Looks like they are doing a good job but need to solve some issues in the updates and organize the page design to avoid being annoying. All fields in the registration page do some kind of verification/validation while the user fills the registration form, per example, the username field checks if the name chosen is available in the database while the user works filling other fields.

4 Y! buzz
I took a look to this site since is similar to Twitter. It is other way to share information. It is Web 2.0 because people provide continuous ranking and comments to current news on the web. The main purpose is that people decide which news are going to be at the top of the news. But there are no following like Twitter. I'm going to keep visiting to check the most relevant news in the world at anytime.

5 Amazon
This site is one of the "We can't live without it". First of all, it provides the market value of most of the products available in the world. When you want to know what is the cost of any product you can go quickly to check in Amazon or Ebay. Second, it is very easy to use for buyers as well as sellers. And third, the system works very well. Everybody has good experience using it. After couples of mouse clicks the buyers can sit and wait for the package at home. One of the reason is considered Web 2.0 is because the content is provided by users. Starting with sellers who put their products on sale at the prize they want with descriptions, images even videos; until customers who buy whatever they want and rate products as well as sellers.

The main difference with its competitor, Ebay, is that in addition to regular selling, Ebay includes bids as an option to make deals. Other difference is that Amazon gives a felling of more secure and serious marketplace, yet both webpages have very well interface and performance, as well as a secure system for payments and no-fraudulent transactions.
