Well, it’s not so much that it really "helps" us as that it would serve to satisfy people’s curiosity about the subject. I’d like to learn more about Rachel and other DB people, and find out what their perceptions of the world are and what their lives are like. I can’t even imagine what it would be like to be missing two of the five senses. I’d be willing to bet that 99% of all people would reach for the .357 or the sleeping pills if they became both deaf and blind. Some of the insights that DB people could give us might be pretty mind broadening. I realize that this forum, if it ever does get created, will never become another Penisarium. Only a handful of people on this board will ever become regular contributors. But it is something we could explore simply for our own intellectual benefit.
On the purely pragmatic side, it could also quite possibly attract sponsors who market products for the DB community, thereby ensuring continued financial security for the message board.
