It's the inverted pyramid that has always been sort of Drupal's niche... a small number of all sites, but a large percent of the largest sites in the world.

And fortunately those of us in tech, the amount of software in the world is exploding so all those lanes are getting bigger, even within their niche.

Thanks for clarifying. I think you're suggesting that there's an "excluded middle" customer that I've just never seen in real life.
