Ask HN: Are we upon the convergence of Apache, Nginx and “other”?

Common wisdom suggests that there are two major web servers: Apache (losing popularity) and Nginx (gaining popularity).

However, a look at the latest trends[1] suggests that we are upon the age of a "triple convergence" in popularity between Apache, Nginx, and the mysterious "other" category.

Which leads to the logical questions: What is the "other" category? How did it become so big? And does it threaten the rule of the Spartan Apachinexology?
