Niche culture and cultural fragmentation

Today we have spoken about niche cultures. We all have a mix of generic and specific interests concerning to the different topics. One issue, pointed to the fact from some critics, says that niche culture leads to cultural fragmentation. But in my opinion, it is not that bad, if there is something for everybody. The world is full of different sorts of persons and cultures. Why should everyone have the same interest? Surely, there might be a lack of continuity, but it is also somewhere boring. Why should everyone be interested in the same topic? Furthermore, cultural fragmentation could enhance creativity and support diversity. I think that makes us a kind of special. There plenty of ideas and concerns, and you nearly find everywhere people, who pay attention to that, no matter how weird the interest is, no matter which sort of niche it includes. In my view, cultural diversity is necessary for guaranteeing what makes us different and how we interact.
