The last chapter introduced the idea of receptivity. This implied that we range from low to high in how receptive we are to adopting your digital innovation. Despite what our friends advise us about your meme, we don't always "check it out." We don't always register. Or download. Or use it (or use it often). Or recommend it. Or pay for it. All of these are indicators as to whether we were receptive to your meme—or content to have it blocked by our bottlenecks, like so much other noise on the network.
