Nice, though I think our intro modal is a bit long (as in, too many pages to explain what you're doing). Just give people the gist of it, and they'll learn the interface as they go, if you've captured their interest, and if you've got the UX right. Speaking of UX, up and down arrows are not indicative up liking/not-liking something. Thumps up, stars, hearts, etc. have done the heavy part of training a user what they mean. Stick to something tried and true, as to not confuse the user. I have to say, I'm not a fan of the horizontal scrolling. What was your logic in deciding on that, rather than vertical?
