After months of invitation-only beta testing, Wave is now open to the public, and anyone can use it for free. Although Google promises that Wave is now faster, more stable and easier to use than in earlier releases, it is not yet refined or tested enough for critical use in business settings. Nevertheless, I'm mentioning it here because it could turn out to be a key collaboration tool down the road.
In the meantime, don't pass up the opportunity to make use of one -- or several -- of the other great collaboration tools in this roundup.
