Well the current implementation only comments on posts that already have a lot of upvotes so it's unlikely that most of the posts are read by humans. As far as I can tell there's no clear path to making any money with it short of becoming a foreign agent or selling upvotes, neither of which I am interested in. So I will shut it off soon because there's not really much else to do.
The replies are believably human, but kind of banal. If anything, this might indicate you've captured the gestalt of the median social media user.
This one was my favorite, and happened to be the only one that got more than one upvote:
> Why are old people so obsessed with collecting things like spoons, thimbles, and shot glasses? It's like they want to have a tiny version of every object in the world.
Just imagine that every comment you responded to was someone else performing the same kind of "experiment." Does it change how much you want to engage with the community?
