If you post an event, poll, page, venue, etc. and check the "Public" checkbox without selecting an audience, your post will not be published anywhere..

This spec really doesn't make sense without another function added so I'm all for removing the Public checkbox for now..

What would be good --

Add a hyperlink to My Home on top of the page before My Groups called "View all Public Posts" which would simply return a page showing a list of all posts where the public checkbox was selected along with an audience or only the public checkbox was selected with no audience
