Goal in long term

• offline notification and chat persistence

Limitation

• one comment can only be referred to one comment at one time using reply button
• same user same time double comment on same post will resulted in undefined behaviour
• only one image per post is allowed, audio/video not supported, post re-delivering not supported
• if A comments on B's post, A does not follow B, and anyone replies A in B's post and then B deletes that post, the notification in A's news page will not disappear, which is what "possibly" means in the notification.
• if A follows B, and B does not follow A and then A deletes his/her account, the "new follower" notification in B's friend page will not disappear
