Google Wave
If you didn´t notice yet, the word Wave pops up in internet more and more. Most of the people using that word sound like they don´t really know what wave is for and all about. But if you combine Wave with Google than something serious is going on and you should update yourself if you don´t want to live behind the moon in the next years.
You can see Wave like the Google imagination of the future of the Internet a.k.a full collaboration in real time. The communicating structures of the Web 2.0 will be enlarged and connected with no more borders between different sites (just Google Products or also externals?).
There are a lot of new features and approaches that are very interesting and show once more the potential that the internet still has. Check out the following video to get more into Wave and therefore into the future of the net.
