Here’s a challenge for some bright intern at Microsoft – write an IE7 add-on that allows GreaseMonkey scripts to run on IE7.
Impossible? Maybe – I’m not sure. But it would be a hell of an add-on!
A really interesting side note: as Better Gmail is a firefox extension, it’s not available for IE users. It’s an interesting twist on the browser wars. In the old days, Microsoft and Netscape fought to lock in users with incompatible extensions. Here we see the same thing happening simply because that one platform is open and the other is not. The users themselves are evolving the browser. There’s no intentional incompatibility (and it’s not in the browser itself). It’s just that one browser is getting more capable than the other as a result of its user community.
