Perhaps the focus shifted.
When I first saw Wolf3D as a kid I was amazed that the computer could do that. Same when I first used a GIS.
These days when people get "excited" about something like Facebook, it's not because it's a technical achievement. It's something more human. Which perhaps is why I don't get it.
Maybe browser technology is "good enough". Perhaps the point is to be able to get apps out to people as simply as possible. It's just a URL.
Due to the fact I don't feel a point coming on any time soon I'll end here.
