Do people generally consider nanomsg to be a "failed experiment"? Is anyone using it for their projects? The author's tone makes it seem like I shouldn't use nanomsg. nanomsg in turn makes it seem like I shouldn't use ZeroMQ. So what would people recommend me to use right now for a project? Are these issues all that serious? My intended use would be for a simple friendly pub-sub API for programs to talk to each other, locally or across a network.
