ABSTRACT
Naturally, the first precondition for the emergence of social uses of participatory radio is exposure. The restricted mobility of receivers among the Tojolabal is a second limitation to exposure. Though most families have portable receivers, it is not a common practice to take the receiver to the work place, because receivers are a very valuable technology to be put to the hardships of the corn field. Contrary to the opinion held by many members of the network's staff, those using the station the most, rather than being women, are in many cases young and adult men, because they have created a wider variety of radio uses than women. A remarkable finding was the tremendous impact that Radio Margaritas has had on local information flow. It is in the convergence of the multiple social uses to which participatory radio is put to where important boundaries of its social value are delineated.
