If you wanted to animate, and didn't have a program, why would you get flash anyway? Wouldn't you rather get a program like Toon Boom which is made specifically for animation?
Besides, Goanimate is a brilliant site for beginners. People who are just starting with animation. Instead of learning how to actually animate, you get to learn how to put together a great video. You learn easily without anywhere near as much time and effort, and see what's good and bad. It's not the animation, it's the entertainment that counts.
If you don't like Goanimate, it's your loss of a great tool.
I'm a proud user of Goanimate, and couldn't care for what you think of it. You obviously don't understand the greatness of it.
Anyway, what would you know?
