Needless to say, you'll have to use it yourself first to truly understand how Google Wave works. Watching the enclosed tutorial video also helps. It's a bit complicated at first but after using it for a while, you'll get used to it pretty quickly. Already, the tech world is abuzz with the potential of Google Wave. Some people even suggested that it might even replace email altogether in the future. Apart from chatting with your friends or colleagues, Google Wave should be really useful for live discussions, presentations, meetings, projects and many more .Currently the Google Wave preview is by invitation only and the only way you can get to use the product is by being invited by a member (like me!). I've got like 5 more invites left, anyone interested?
