I've long been excited by GoAnimate. I've posted all two of my animations in other blog posts. But I've encountered difficulties when students use it. These range from the standard technology issues ("Mr. Cosby! I broke the internet!" One time it was almost literally true.) to simple time-management issues. There were a lot of things about it that my students didn't understand the first time around, and would be able to do better after having some experience with it. there were also some issues sharing the resultant videos, strangely.
But now GoAnimate for Schools is live, and theoretically, it would solve the sharing problem. It also means that the limitations suffered by mere mortals--the character creation difficulties, for example--would also be overcome.
As for my students breaking the Internet, well, I understand it's fragile anyway.
