Tim O’Reilly, for whom I have great respect, has a great post on
O’Reilly radar discussing a breakdown of visitors by browsers they are
using.

Brief summary



This year




Internet Explorer: 54.66%



Firefox: 35.08%



Last year




Internet Explorer: 75.53%



Netscape: 19.89%

The verdict is clear – Firefox is gaining a ton of momentum and there is no sign of slowing down. Hats off!
