I find Acconci's concepts interesting, but I'm not sure if I totally agree with everything he proposes about public spaces. His ideas strike me as a bit cynical, perhaps too exaggerated. While our views of public spaces have certainly changed, I don't think they've changed as drastically as Acconci proposes, nor do I think the change is good or bad. It simply is.
Acconci's discussion of what our public spaces say about ourselves and our specific interactions with one another (Subsection 10) was especially interesting to me. This idea of "payment" is rather vague and again, cynical, but I relate to it on some level. The third-to-last sentence, on the expected roles we play in different public spaces, particularly made sense to me. We go to some public spaces specifically to make human contact, while in others, isolation is the norm.
