Those of you who recently made the switch from Friendster to Facebook are probably familiar with the omnipresent “Can This Pickle Get More Fans Than Nickleback?” group. (Warning: photograph of anthropomorphic pickle engaging in apparently consensual sex act with Chad Kroeger.) The group was founded in February, back when Nickelback’s Facebook page listed 1,380,820 fans. While new Nickelback fans have since trickled in, new fans of the pickle that symbolically opposes Nickelback rushed as a raging torrent, and at some point on Friday afternoon the pickle pulled ahead. Right now, the pickle has 1,456,556 fans, while the group Billboard two months ago declared the Band of the Decade has 1,418,801. On Facebook, at least, This Pickle has more fans than Nickelback. Which raises some interesting questions.
