Idea of next social network: dedicated social networks

Nowadays a lot of social networking apps are on the market, like Facebook, Instagram, Twitter to name a few. But these are all generalized social networks in my point of view. By generalized I mean: people can share almost anything here, on any topic, discussions arent much centralized on specific topics. What I think is, dedicated social networks could be game-changer Like for each thing, we can have one. For example, for only film-related discussions and content sharing we can have one dedicated social network. I know, people will think, that this way there would be a flood of social networks, but that's the beauty. Content creators for specific topics can go to a specific social network, that has the community, for them. For example, a lot of people post videos about films, theories, trailer breakdowns on youtube. so they can post their content on the dedicated social network for films. And why I am mentioning dedicated social networks for films so much, bcoz I have created one. www.filmsta.in its in early-stage, testing phase, but you can checkout. And comment down your feedback. will It be a success, will people like it?? That's a big question...
