To think, it was about this time last year that Google first unveiled its "collaboration tool" Wave, and today the company's taking out the invitational step and opening it to the public at large -- which begs the question, did anyone not have an invite that wanted one at this point? It'll also be now available in the enterprise-centric Apps suite for no extra charge. On the developer side of things, expect some more open source code be unleashed, including most importantly the rich text editor. Can't say we've really dug around in the service ourselves sinc
