How does Social Discussion works? What to expect?


I have set up Social Discussion addon for the Comment Plus plugin. I started a test conversation by posting a comment in the website and make it automatically post to twitter and facebook. I then replied to the comments posted from twitter and from facebook, but I´m not getting those reactions comming back to the site.

How this function? The reactions are pulled automatically or they need some time? How can I know if evrything is working find?
