It's a long time since i wrote the last article, but now i don't have another choice.
Perhaps you have heard of the new
google wave, which will be available later this year. Wave is a new way of communication - it's a bit like email, wiki and instant messaging in one tool.
So, in wave it's possible to simply write a wave to someone else or to more than one recipient. Exactly like you do it with emails by now.
But it's also possible to edit the received email, comment on parts or the whole message and do many other great things. After that, you can share the whole communication process with someone else (there is a replay button so everyone can see who wrote something and in which order).
By this functionality you can start with an email, working on it with some friends or colleagues and after a while creating something you needed a wiki for by now.
Another application is instant messaging. The communication in wave is as fast as instant messaging (or even faster, by transmitting every single character!), so instead of switching between emailing and instand messaging you can simply use the same tool for both.
