It could only work for people who strongly believe in them -
knowing that it exist does not = believe - Little to do with
genders - except with the points that RAW spoke which is quite
debatable. 
People are easily misled - such level of communication will often
spark interest because most people doesn't have specific enough
target in their life. With zero kind of requirement they are
looking for - anyone would fill the bill - decent looking, decent
character, etc. Everyone only need to feel comfortable with each
other, overflowing emotions, someone made the move, both agreed, a
relation formed 
Ask what are the physical and characteristic you are LOOKING for in
a person - nearly 70% will tell you either don't know or anything
is general.
Drama mode on:
'I want a caring guy'
'Yeah I know you looking for a guy that is caring, about 0.2
millions brother Joes in SG fits the role. Take your pick.'
People dunno what they want... so they are the ones who cannot
differentiate platonic friendship from a potential - because anyone
*SEEMED* to fit the bill. People end up going through series of
relations, each relation gone and they learned. With time, people
will finally find and settle with this one person - from fallen
dreams, reality, lesson learned, etc - the partner that would walk
down the path of life with you.
