That's interesting that they both had it on their lists despite not knowing each other. Over the past few years, I've actually been seeing it less than I used to. It did increase in popularity in the U.S. between 2009 and 2010, but it's still pretty low on the top 1,000 list (it was #904 in 2010). Perhaps it's continuing to rise in popularity, though. Or maybe it's more popular in your area than in other places?
