We need to have some sort of comparison function where you can tell whose list is most similar or most different compared to yours.
@silesian - I assume you must put these in some sort of spreadsheet. When you've got that done, if you can send me a copy I'll see about writing some analysis code. I don't think it should be too hard (famous last words), and like I said, it might be interesting. I'd generate a similarity score for each pair of people and then report those in a table or something.
