I think you're misunderstanding what our channels feature entails. It is intended for the site administrators to be able to push the website content to their Facebook pages or groups. For instance, a new article or post could be easily shared on a Page's timeline feed, Twitter Stream and LinkedIn Company Page all at once. The activity of registered users would not be involved in this.
Separate from our channels, we do provide an Open Graph plugin for EasySocial that allows some posting of EasySocial activity on a user's timeline. However, the capabilities of this plugin are currently pretty limited for the type of actions we support (currently we only post an action for uploading an image in ES).
I hope this helps clarify your issue, but please let us know if you need more details or have further questions.
Thanks
