Facebook has quietly rolled out the Ask feature on its site, giving users the opportunity to flesh out the data that they can't see on a friend's page. The less information the person has made public on their profile, the more there is to Ask.

Whether it's more general details of where they work and where they went to school, or more specific information such as a person's address, phone number or email address everything is up for grabs.

When the info is requested, the user will receive a notification from that friend (along with a personal message if they chose to write one) and then a list of options for replying -- options that are themselves taken from other friends' profiles.

While a person's hometown or workplace might be fairly straightforward, the option to ask a person's relationship status has raised a few eyebrows. After all, what if "it's complicated"?

Either way, there's no obligation to reply to the questions. But it could lead some Facebook users to question whether they really want to be handing out that info to the thousands of 'friends' they've accumulated over the years.
