How many conferences would you have seen ten years ago with a prominent lisp showing? IIRC even the primary (at the time) ILC conference was only held every other year. These days with more regional conferences starting it's nearly in the twenties, and attendance at Strange Loop (which has had lots of keynotes by lispers) is several thousand and growing.
