I wondered this recently myself. I think the reason we don't see it is because we're part of a certain niche in the cigar world. If you take the time to connect to the internet and discuss cigars with others then you are in a fairly new school group of cigar lovers. Even if you've been smoking cigars since Cubans were legal in the US.
There are many, many more people that don't get into this like we do. Anytime I spend an afternoon at the B&M I always hear at least a few people that have never heard of Tatuaje, illusione or even Pepin! <GASP!> And if you see a young newbie come in to try out a smoke he'll always grab the Macanudos or Cohibas - name recognition!
Seems like stories conflict on this though. I've also heard that Acid is the most popular, and Macanudo - and
this article from CA says that Tatuaje is top dog - followed by Padron and the OpusX.
