If your UI requires that users "be attentive" just to discover the content you're trying to convey, then your UI is awful and the user's failure to see it is entirely your fault.
Of course design elements (color, typeface, white space, etc) are important...but visitors of your site are interested in consuming content NOW (not a few seconds form now). People are lazy.
Design-by-group tends to produce boring, cluttered, seen-it-before layouts with little innovation. This seems to be on the completely opposite end of the spectrum -- with no one saying, "Uh, wait -- I think you need to make it clear that you can scroll for more info."
(And also: "Uh, I'm not sure developers are going to take kindly to Google requesting access to their microphones so soon after the NSA revelations.")
