Describe some website features you have encountered that you would consider to be web applications. What does the application do? How do you think it works? Does it use a database, send e-mail, or perform calculations?
Briefly analyze your chosen site feature from both a technical and business perspective. Be sure to provide the URL of the page that you are discussing. Take a look at the applications suggested by others to see what you think of them. How could they be improved? Be sure that any sites you suggest are legal, not offensive, free, and do not require users to register.
