A nice follow-up by John Gruber to Joel Spolsky’s essay from last week:

I’ve been thinking about the rise of the web as an application platform for a while. But what hadn’t occurred to me until I read Spolsky’s essay last week is this, which I think is quite remarkable: Microsoft totally fucked up when they took aim at Netscape. It wasn’t Netscape that was a threat to Windows as an application platform, it was the web itself.
