Extreme Remote: Product Management - Online conversations

Since the product owner is not within hearing distance of the remote team members (or not even awake when they are discussing issues), you absolutely must create a vibrant and effective online conversation.  Many tools such as HipChat and Slack support group chats.  Make this the primary way that issues get discussed.  And, have questions for the product owner clearly labeled so that they can focus on the product issues rather than all of the other technical discussions.
