Thoughts about collaboration
To collaborate is to work together in an intellectual effort. It is different to inviting someone to participate in an already established platform. It allows for flexibility and negotiation between the participants.
There are still questions about how people can collaborate on a project... hence, this brings up the inability of the viewer in finding a space in the work of art -object, event, video, etc.- It raises the issue whether a "passive" participation can be considered collaboration at all.
There maybe an expectation, from the artist or cultural practitioner, about how people should engage with the work or work-platform. This points out to separation, distance, and misunderstanding, indeed to the impossibility of collaboration in art.
