The call for new forms of participation has become common in the public sphere, promising renewed forms of public engagement, more efficient industrial processes, and more democratic decision-making processes. Technological innovation is a particular case when considering current discourses of participation. It is both problematised as needing more developed or open forms of participation, and proposed as a mean for experimenting with original participatory formats, for example, in: crowdfunding, citizen science, amateur reviewing/rating, online communities for public debates, consumer participation in (participatory) product design.
