In the Week 6 discussion, you found some interesting web sites.  They presented examples of some of the trade-offs you need to make during design. 

Some examples of possible trade-offs I saw in your sites are:

1. Should pop-up ads be used? Several sites used pop-up ads. Ad revenue is necessary to fund the operation of many sites. What is the best way to retain users and generate revenue? (pop-up or normal ads?) 

2. How much advanced technology should be used?  The http://my.yahoo.com example uses AJAX technology that allows users to drag objects in the windows to different locations and then the screen is quickly repainted just like a desktop application.  Do enough users of your site have recent browser releases to take advantage of this technology?  

3. Some of the sites had fairly slow response times. What is the proper trade-off between hardware expense, development time, and the level of resources allowed to be consumed by each web page?  Should some features be eliminated or redesigned for better performance?

4. How much input can you ask users to provide in exchange for allowing them to use the site? Will the users you really want to attract be willing to complete the registration process?
