Creative Labs owned the openal.org domain name, and let it lapse, so I 
bought at auction--for a lot of money!--to protect it from falling into 
the hands of a domain squatter.

What's on openal.org right now was just the minimum needed to let it 
continue to have a web presence, but there's no reason this can't be 
improved. Jack Slater put together a basic template and we bought some 
stock images. I think it looks clean and professional, but we 
_definitely_ don't have much content on it.

It is not. It's similar to GLUT vs OpenGL, as far as I know.

OpenAL Soft is the only thing listed on https://www.openal.org/links/ 
(the "Links" tab at the top of the page).

> PD. Icculus got the "OpenAL Extension Registry". Where did it go?

It was held together with some really old software and I didn't think 
anyone was using it anymore. I can put it back up in some form. Also, it 
(or something like it) can go on openal.org now that we actually own the 
domain, instead of it sitting on an otherwise-unrelated domain.
