Yeah, that was a bit confusing. Let me try again:
I can see having a button or Javascript 'hover box' that shows as you navigate your site on every page. This box would only be shown to certain groups of users, like admins. While navigating the site, the box would say "Post this to: Twitter, Facebook, Pinterest, etc" with a message box. Then, the user/admin could easily be on any page of the site and have a very easy way to 'push' that content to a social network Facebook Page, Twitter Feed, etc.
So, it wouldn't be automated, but hopefully much easier.
Hope that explains better.
