Facebook wants your address and mobile phone number.
But it’s not sure exactly how to ask.
It’s a complicated digital courtship, particularly because Facebook doesn’t just want this data for itself — it wants to “share” this info with all of its friends, which in this case happens to be app developers (think FarmVille, Compare People and Where I’ve Been — all that non-Facebook stuff that pops up in your news feed).
