Daniel is listed in the writings and not the prophets because a jewish prophet was someone who spoke the word of God to the people. Daniel spoke to the king not the people. It is not until the end times that daniel comes into his inheretance...He will arise about the same time as there is "one on this side of the riverbank and another on that side of the riverbank"[tigris]
At that time the words of daniel to the "king of babylon" will find their mark and daniel will begin to speak to his people.
