This is the digital equivalent of giving me a magazine to read, waiting until you're sure I've got my eyes on it, then shoving a business card in my field of vision
This is an ironic analogy to choose, seeing as how magazines do in fact do exactly that.
I know it's been a while since anybody read one, but if you cast your mind back, you'll recall that every dozen pages or so they will have stuck in a subscription card that you'll have to shake out or even tear apart just to continue reading.
It funny in a way to see that digital media has so exactly copied that.
