Yesterday as I was listening to several conversations, I had the feeling that I ought to drop Safari and move to Firefox as my browser. I love Safari because its slick and fast, but Firefox is becoming a platform. Because of its open architecture, there are thousands of people building things for it. That's a powerful force that Safari will never match unless they also open their platform.
Mike Shaver was supposed to speak on Firefox, but he couldn't make it. I didn't catch the name of the guy who filled in for him. He talked about the open standards that Firefox is built upon (like RDF and XUL) and showed some of the cool things people are doing. That cemented it. I'm switching.
