Bit weird - just installed both these apps and Facebook has completely revamped it's list of 'people you may know' - including 4 happily married acquaintances - 3 of whom have been in my contacts list & living nearby for years. FB never thought to recommend any of them til now. Please tell me it's just a co-incidence and they're not all cheating or thinking of cheating. Not my business I guess, but it's made me feel a bit cynical.
