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 since its beta launched, but co-creator Lars Rasmussen tells us we should be giving it another go. He further acknowledged that they've got some work to do on educating users on the best ways to use the service, which at this point seems to be mid- and small-scale collaboration. To that end, expect some new tutorial videos, and with any luck, some amusing animation.
