Still the Segregation in Browsers Exists

Today, I was doing the so called load testing, along with my colleagues in my project. But this screen turned me off. Why cant applications be compatible with all kind of browsers. The basic work done by Netscape or an IE or fire-fox in fetching pages will be same.

Why can't then application use features common across browsers, as many things are getting standardized day-by- day. These basic things must be kept in mind while developing a web application.


I think every on must have a look on developing application simpler , but effective one.
