It doesn't provide everything that flash does, and IIRC only supports flash animations. Some things that flash provides that JavaScript (at least JS provided by the server) can't provide: Webcam and microphone access (think sites like ustream and stickam), exact font control (there was a demo site a while back that showed the same site rendered on different browsers to demonstrate how much even the placement of fonts differed), etc.<p>I'm no proponent of Flash, but to say that Gordon can completely replace Flash is not the truth.
