> Shall we give the real data, no data, or simulated data. Or even a selected subset of real+fake data. (With the ability to define sets that could be reused across application.) Sometimes I want the app to have access to some of my contacts, but not all of them. For example, my work contacts but not my personal friends, or vice versa. Or simply "my contacts that told me they were also using this app". PLUS hundred fake contacts to poison the data.
