You create a topic and someone has commented that. After 15-20 hours a second comment is posted. So what kind of stories do we have? 1)Person X created a topic A. 2)Person Y has commented the topic A. 3)Person Z commented the topic A. This looks like redundancy. It is possible to read the same stories again and again and again. Solution for that could be: Identical stories should be replaced. So story number 2 should be removed and story number 3 takes his place.
