Does Comments Plus go out and find tweets/Fb comments & pull them in?

I'm trying to decide between comments plus and Social: http://wordpress.org/extend/plugins/social

One feature Social has is that it essentially crawls public Fb posts and Twitter and pulls in comments/shares that may not have been made from the plugin's front-end interface. Does Comments Plus do this as well?

Also, will it get G+ support when that api is avialable?
