Requirements:

• multiple sources of input (social media content) into a system
• multiple destinations of output (social media api's)
• sources and destinations WILL be added

some pseudo:

IContentProvider contentProvider = context.getBean("contentProvider");
List<Content> toPost = contentProvider.getContent();

for (Content c : toPost) {
    SocialMediaPresence smPresence = socialMediaService.getSMPresenceBySomeId(c.getDestId());
    smPresence.hasTwitter(); smPresence.hasFacebook(); //just to show what this is
    smPresence.postContent(c); //post content could fail for some SM platforms, but shoulnd't be lost forever
}

So now I run out of steam, I need to know what content has been successfully posted, and if it hasn't gone too all platforms, or if another platform were added in the future that content needs to go out for it as well (therefore my content provider will need to not only know if content has gone out, but for what platforms). I'm not looking for code, although sample/pseudo is fine... I'm looking for an approach to this problem that I can implement
