Google+ is a social network. As such, I have a hard time imagining that it can be successful by forcing users to use it in a specific way. If the people using the service want to leverage the service in a certain way, there doesn't seem to be anything "wrong" with that. In fact, I'd argue that Google should take such usage as feedback into improving the service to better incorporate the new usage patterns.

EDIT: This perhaps should go as it's own comment, but I'm going to throw it here for the time being:

People like to use social networks as a public publishing platform as well as a way to share with friends. This is to some extent supported by Google, as they have encouraged people to use G+ as a blogging platform. The behavior we see with the HN circle is (I'd argue) just people attempting to hack functionality onto public side of G+, which IMHO is a part of G+ that is sorely lacking.
