I haven't yet read the article, but I'm pretty sure Bitcoin's not mentioned. But, as we're all well aware, some of the mentioned movements have accepted Bitcoin donations.

Image, if you will, Bitcoin taking off, in a very big way, next year (or 2013), and did so in such a way--making a tremendous impact--it's not outside the realm of possibility to see Bitcoin as the Person(?) of the Year on the cover of Time.
