Starting today, we are making Google Wave openly available to everyone as part of Google Labs. You no longer need an invitation to wave — simply visit wave.google.com and sign right in. Likewise, if you are a Google Apps administrator at a business, school or organization, you can now easily enable Google Wave for all your users at no extra cost (more on our Enterprise blog).
We began previewing Google Wave with individuals and a handful of Google Apps customers six months ago. Since then, Wave has been used in a great many interesting ways. It’s clear from the invaluable feedback we’ve received that Wave is a great place to get work done, in particular for teams working together on projects that involve lots of discussion and close coordination.
If you tried Google Wave out a while ago, and found it not quite ready for real use, now is a good time to come back for a second try. Wave is much faster and much more stable than when we began the preview, and we have worked hard to make Wave easier to use. For example, you can now get email notifications when waves change, easily navigate to unread parts of a wave, and remove participants added by mistake. We have also added permission management options and an extensions gallery.
