I am shocked and chagrined! I know you like to play the older, wiser, experienced, educated, "I'm a pimp", whatever card, but give people a little more credit. You might share a condition with Stan Marsh. Often people are using simple metrics like how much a school is "liked" as a proxy for all the stats we're talking about right now. The quickest way to value something is to look at how it's trading in a market and look at historical payoffs. Is it incomplete? Of course. Does it get the prospective students the lion's share of information they need? Yes.I hate pretty much all of Andy's list
Try to find one example of a prospective student asking things like "is the guy that teaches econometrics good at school X".
Perhaps I'm taking too much liberty with your "like" qualifier, but people ask all the time about what content schools cover. They ask questions about how well coding is integrated with theory. They ask what programming languages are taught.
On another note I think a lot of the questions being suggested here are quite good but I do concur that they should be divided into different priorities as sleekmover suggested:
Shared Information should be like a mini skirt: long enough to cover everything, but short enough to keep it interesting ...
I think we should classify information as Must Have, Should Have, Could have. Give this list to programs, assign weights accordingly and rank them later on on Transparency of information based on the information they provide and the score they get.
