may be esoteric, but people will be interested if they are actually discovered

I have to admit that LIGO is a more appealing project to an "armchair" physics geek. (a.k.a. "dilettante")
do you mean because it seems so esoteric? If these signals really are detected - basically, sound waves in the human hearing range - this will open up a new field of 'audio astronomy' which has never existed before - it's all been optical and other EM so far. Imagine hearing and knowing of the forest of sounds I mentioned here - this makes the project more than a purely abstract exercise ..
