Plenty Of Fish Where The Fish Are.
This is a snap of the analog equivalent of Subway Crush and happn.com that appears in a free paper distributed at railway stations in the UK.
I don't know how many connections are made, but I'd imagine it's not a large number given the randomness of the process and the paucity of recent activity on Subway Crush.
But here it's even less likely to happen because, as the guy who tweeted this points out, she's an avid book-reader being targetted with a message in a publication she clearly ignores. A perfect example of focussing on the broadcast to the exclusion of the recipient.
Now, the people selling ad space in the free paper would identify the woman as typical of their target demographic - something like literate aspirational commuter. A perfect example of focussing on categorising the consumer rather than understanding the context of the experience.
Fish where the fish are.
