Maybe it does, maybe it doesn't. Most facebook controls are buried three levels of counterintuitive links down in a locked filing cabinet in a disused lavatory with a sign on the door saying "Beware of the Leopard".

Or to put it another way, if I can't figure out how to make facebook show me stuff that isn't shite, how are ordinary people going to figure it out?

edit: Also I've figured out that the reason I no longer hear from an awful lot of my facebook friends is that I've probably set at least half of 'em to "ignore" due to 'em posting too much garbage.
