While there is plenty of information on the Internet, sometimes it is confusing, incomplete, or downright wrong. It would be nice to have a place for like-minded individuals to share their thoughts on the subject and for people to easily get their questions answered, assuming they can tolerate the occasional abuse. Granted, one can just post it under miscellaneous audio, but then, as @hilde45 implies, everything can be considered to be under miscellaneous audio.
It also helps codify its importance, which is far greater than cables. It is not like we are asking for a separate topic section for fuses. This does not mean that fuses are not important, but they are far less important and influential than room acoustics. IMO
