Well, AW must the best/most efficient option a the moment.
Personally, I'm not overtly happy with it, but can not complain too much either.
AW just got something about it , and also the fact that its meant exclusively for advertising sexual services (e.g. as to opposed viva street or CL) I does get boring at times, it would be nice and healthy to see some alternative sites , but the truth is, those are just not viable and therefore are waste of time and money at the moment.
Its a vicious circle,in order for a change to happen ,we, as consumers ( both service providers and the users) would have to initiate it. ( which is highly unlikely) So there.
