Google just announced its newest product ‘Wave’ that is coming this year. Wave has the ability to change the way everybody communicates, forever, in much the same way that email did when it became common place.
It combines aspects of Wikis, IM, Email and version control into a single product that changes the way people communicate. I can already see how it would make communicating with family, friends and coworkers much more fun and immediate. Click the link for more info and a loooooong video demonstration of it in action. If you are not excited about it, you don’t know enough about it yet.
