It's been over for a long time
Anyone who runs a real, mainstream Web site has known for at least three years that the browser war is over. Geek sites attract a nonrepresentative sample that masks the extent of Microsoft's domination of the browser marketplace.
AOL may ignite a new browser war as it maneuvers to push TimeWarner/CNN content into the faces of users -- but it does not yet have much of an arsenal and continues to be dependent on Microsoft for its primary browser technology.
Mozilla/Netscape 6.0 is a disaster. It has lost its way in its own religion. Rather than writing code that works -- which OUGHT to be the goal of any developer -- the Mozilla effort has yielded an abstract user-interface model that is theoretically cool and practically unusable. The same can be said of the rendering engine, standards-compliant but real-world ignorant. The Web that Ought to Be is one thing, but we have to use the Web that Is.
Konqueror is an admirable effort, but it's a long way from being finished, it's not as fast as it should be, and (for reasons I have not been able to track down) it really loves goofy fonts.
