I would like to be able to pronounce the name in a sensible quick fashion based on how it is written. ;)

For "WebScript" that works. Even just "JS" works. For "ECMAScript" not so much.

ES would be fine. I guess it would conflict with with Spanish domains. But I'm sure we can just continue using .js in the files names... What is the Oracle gonna do? Sue every body who uses .js in the filename?
