Scoble asks a generally good question about the browser business:

Finally, I'm gonna ask a provocative business question of Opera (and other browser manufacturers): What's your business again? If all the browsers have the same underlying features, and they should only add things that are standards, what differentiation are you offering your customers and investors? Are you saying Firefox's developers can't propose anything new that'd push the Web forward? Hey, how about some linking technologies like Greasemonkey? Is Firefox not allowed to add anything like that that the W3C didn't propose and that the WaSP didn't approve of?

I'd take it a lot more seriously if IE didn't screw up my css fairly regularly - and if the IE team weren't already backing off of supportinf css properly in IE7.
