When the failures are limited to obscure implementations, and/or popular ones with a hope of being updated, I'm in the "fix your shit" camp. When a substantial fraction of the internet breaks, this approach is less clearly the right one because it can result in the never-ending downgrade dance, or in limited deployment of new versions/ossification. I hope (with no real evidence) that given the strong level of involvement of the major browsers in 1.3 development that advantage goes to the client. Kyle
