I would love to be able to flag a post as public but also only make it appear in specific circles streams. My Google+ followers are mostly migrated from Twitter and they are mostly technical users with a lot of JS background. This means I don't want to spam them with "funny" pictures or one-off comments about strange stuff, maybe even local to where I live. I DO want to post that stuff to my coworkers though as they are at least moderately interested and posting it to Google+ is less annoying than email for all of us. I can already limit these posts to the "Coworkers" circle, but that means that the post is now not public any more. People looking at my profile don't see it. I can't link it directly and when a recipient decides to reshare, they get a (otherwise well-meaning) warning, even though the post is totally non-private - I just didn't want to spam my JS followers with that. This is a shame because with Google+, I finally found an outlet where I can post stuff for the various groups of people without spamming others.
