Replying to Social Contacts
This version of CCP does not include any reply UI. While some reply user interfaces will be built in future sprints, it's important to consider that even in the shipping version of CCP there will be some social contacts where the agent must pop out to a browser to reply. For example, if the post is a blog. It may very well be impossible for CCP to present a UI to navigate through the steps required to allow the agent to comment on that blog. There could be registration, captcha, etc. Therefore the CCP solution will always have the notion of an agent stepping outside the boundaries of the CCP software to "handle" a work item and then reporting back to CCP on how the contact was handled.
Still, even with the extremly limited functionality in Sprint 13, CCP could be reasonable used to monitor/reply to twitter.
