I really like this sort of stuff, and the home page is very pretty (and also professional looking). I balked at the sign-up and get a reference code on the Facebook page though.
I have just joined the project and am no biology expert, but all of these discussions are help with professional biologists on the Slack page of the project. Let me know if you'd like to join and I'll invite you to Slack channel of the project.
Too bad, one has to sign up, otherwise I'd be very interested in such a interactive document.
EDIT: Ah, it's Alpha. That's why you need to register. Makes sense.
