Have you heard of Mozilla's Ubiquity? I think it's the beginning of something big.
Ubiquity is a Mozilla Labs experiment into connecting the Web with language in an attempt to find new user interfaces that could make it possible for everyone to do common Web tasks more quickly and easily.
It's going to change how people interact with the web. I don't know how exactly waht it's going to turn in to, but it's a project that I'm going to be watching.
