Comment on a post. A comment to a post displays below the original post.
Reply to another member’s comment. This inserts the name of the person to which you are replying at the beginning of a response.
Share a Post. It is easy to share posts from your stream with your Circles or in Communities using the Share button. 
Compose a Post. You can see a slight difference in the post box when you are posting to Public or your Circles versus to a Community. In a Community you don’t have to direct the post to someone, rather you post it to a category. Both posts offer the same embed options (you can only embed one link although you can include multiple links in the body of the post).
