When did I meet them???

Facebook has a rarely used ' I know so and so thru...'' feature whe you become friends w someone.

But some times I really want to know when and under what circumstances I met some people which I'd like to have for every person on facebook.

wonder if it's doable and useful

Google AdSense - Screening

So as a Harvard student, Google's archaic (ha!) web crawling/email reading technology always shows me ads for Harvard admissions etc. And all these services that I don't need. So why don't advertisers have the option for screening, i.e. they can say don't show ads to people with @fas.harvard.edu addresses?
