The irony here, as I see it, is that an old, insecure feature Microsoft built to try to beat Netscape is now being used by Microsoft’s biggest current rival to patch IE. The upside for developers is that Microsoft is going to have a hard time killing Chrome Frame because it actually does the right thing — it’s not hacking IE via undocumented APIs or unscrupulous haxie-like code injection. They used Microsoft’s own well-documented and fully supported platform to do this. Bravo indeed, Google.
Interesting insight and some technical stuff on Google Chrome Frame.
