On mobile at least (through the HACK iOS app), this is a stunning failure of marketing. Absolutely no clue what it is, what it does, what market it is targeting, or how it benefits me. Why should I sign up if I have zero clue what it’s about? I am not a fan of marketing sites, but anything more than just a sign-up form and a one-line call to action would have helped immensely.
