Another clarification on open structures of participation is the conflation made between distributed computation and distributed interpretation (or distributed science). The most famous is the much celebrated distributed computation project: SETI@home (see also folding@home, et al). While lay persons can participate in this distributed science project, they are conflated with their machine. The participant may know nothing about fast fourier transforms(fft) and signal processing before they download the screen saver. After years of use, they will still know nothing about ffts and signal analysis, that is, they have lent their spare computation cycles, and are not invited into the interpretive work. As a model of distributed or participatory science, this fails.
