The Future Is Now
So what's next with the web? Will we see the next big thing come when CSS3 gets adopted? Will there be a revolution on the Internet when browsers support XHTML 2? No, of course not. These things might make life easier for us, but they aren't going to change what we can do right now. We already have all the tools we need.
So what does this mean? It means we're not waiting for anything except new ideas. Whatever the coolest, greatest new thing will be in 2010 will probably have been possible right now, if only we could have thought of it.
It's only our perception that changes over time. For example, Google Maps used technology that was there for years to do something very useful, and it pushed the limits of what we thought were possible in a web page. And it didn't take long for Microsoft and Yahoo to roll out their imitations. We could have had maps like this years before, if only someone would have thought of it.
It'll take some time to explore what other possibilities exist in the technology we have available. But there's no need to wait around. Let's see what's possible today.
