I suspect that, like most things, there are benefits but you must be prudent about dotting the "i"s and crossing the "t"s. Oz recently had a case where someone grieving over the death of a family member had their Facebook inundated with outrageously criminal defamation because they hadn't ticked various boxes in their setup. I gather the US has experienced similar situations; there are some seriously disturbed people out there and it seems that Facebook merely shrugs its metaphoric shoulders.

But those who indulge and who 'keep the doors and windows locked' seem to have the same enjoyment as any householder who does the same.
