New tool on Facebook

While the social media site has had an option to 'ask' for a friend's phone number, address and e-mail for some months now, the relationship status 'ask' button is a new development - and not everyone is happy about it.

Others called it "naggy" and questioned its necessity, with one person writing: "How awkward is that Facebook devoted a single button to ask your friends why they're single?"

Even more people have asserted that the button is just another move Facebook has taken to exploit users' private information.
