The revolution started with the iPhone.
With the launch of their breakthrough device they didn't intend for developers to be making Apps. Apple instead believed that developers would make web apps using HTML5 and save the web app as an icon of their phone. Surprisingly open by Apple's standards the strategy soon changed to native apps because web apps simply didn't feel quick enough.
Web technology is getting better
However, as HTML5 becomes a standard on PCs everywhere web apps are approaching the same sophistication as native applications. The hardest step now is for developers to take the plunge and create these great new interfaces and not get stuck in the old way of thinking and just pushing out another blog.
One of my favorite designers, Dustin Curtis, is leading the way with this new UI element on his site; the Kudos button.
It looks great. It's fun to use and it's a really simple way to add some life to a site. It doesn't work on touch interfaces for obvious reasons. Sadly Dustin hasn't made the code available yet, but most programmers could probably copy the concept. It's that easy. We just have to make sure we starting thinking less about static web and more about user interaction.
