I also found it difficult to navigate to something which actually shows your product. When I realized that the Mandarin demo was your product demo, well, I've seen that approach in enough textbooks and it's nice to implement via animation. With some more polish and a broader test sample, I'd probably recommend it - as much as the "behold, science!" presentation annoys me.
But then when I went back to your home page IT WASN'T THERE ANYMORE. Please don't ever, ever use cookies to do that.
Feel free to ask me about the science if you'd like. It's hard to strike a balance between advertising what we think is most important and comprehensible, and sounding too mystical.
Sorry about the disappearing splash page - I know what you mean, and we'll have to think about a better way of letting people get back to that, while still making the dashboard for logged-in users primary.
Yours, Greg
