I suggest a compromise. Two Topics. First one is where he posts the new ones, second one is the archive of the News posted before. It could work like this:
1. Topic --> The Exit Reporters #8 (new one) --> edit post and write new one in here, edit topic name too of course
The Exit Reporters #7 (the one before that obv

) --> delete and move (c/p) to
2. Topic (archive)
The Exit Reporters #7 (copy paste from the first topic) --> new post in archive topic
The Exit Reporters #6
The Exit Reporters #5
....
This way, at least, you would have one sticky news topic and because of the second one (archive) there don't have to be new topics for each News Thread.
