Selecting the Right Target

Selecting the Right Target

It's sad but true that few people bother with the Google+ hashtags, either relying on an automatic selection of leaving their posts with none. However, it also seems few people use their Circles effectively, either, and one culprit is the ability to post to Public, meaning anyone who has them in their Circles. This annoys me greatly as I mostly have people in my Circles for a given reason (e.g. genealogy), and so receiving posts about cooking, religious messages, etc., is inappropriate. Those posters could have shared with a specific Circle, or the customisable 'Your Circles' target, but no thought was really given to their audience.
 
Is this a problem with the Google+ concept, or a lack of education?
