I ran across these post-its notes at Café Sport in Horta, Azores. They feature various questions and messages about sailing crew. You want to go to Marseilles? Bermudas? You have certain kinds of skills, help yourself.

These inscriptions are interesting as they show the social importance of certain places where people could access this kind of messages. Sailors know that if they show up at this café, they might meet like-minded people to help them. Life being what it is, social interactions are generally asynchronous, which is nicely supported by the yellow inventions of 3M: post-its notes (printed and folded A4 papers too).

The place enable a sort of filtering: in terms of people who come over here, and in terms of messages that can be exchanged. One of the dream of location-based platform designers (and the social media crowd) is to enable this kind of touchpoint with digital tools. This is by the way a topic we will address at Lift11 in Geneva.
