i would say is not to approach or to be approached by people with specific goals in mind..
it's better to play it cool, meet people, get to know them, and then see if there is an interest for anything more..
i think people aren;t patient anymore..everyone is on the hunt for that "perfect" someone..and they won;t "waste their time" (to put it bluntly) just to make new friends..unfortunately..they're ok being with the ones they already have..it's a real piss off.
