I was referring to current Adsense publishers. I half expect an email on or about March 1 of this year notifying me that I have until June 1st to establish a G+ account and that if I don't cooperate G will terminate my Adsense account. (The email will, no doubt, outline in hipster fashion all the "cool" features of G+ about which L. Page is "super excited.")
Of course, it would make no sense for Google to bite those million or so hands that help feed it... or would it?
