Find novel way to make a 20-questions-esque way to arrive at the right one
Preferably not a hard coded diagram/flow but instead work off of tags or whatever (freebase style?)
Don't deal in mathematical/physics stuff at first, this is more for discussion use...but the system should be abstract enough for anyone to plug a list of things (and associated metadata) to make an answer easily derivable
Future: maybe expandable w/ some form of NLP to make suggestions as one types?
I would also like to see this for different things like discussion abbreviations e.g. "e.g.", "i.e.", "ca", "née", "etc", etc
