1) it's already the case. PR firms have created many credible user accounts in most social media, maintain them for a long time, and now use them to influence it on day to day basis. I bet even HN has some of those. 2) already the case. it's called world of mouth. we just use technology to propagate it now. We never had so many chat apps, social networks, content sharing services, etc. 3) this I want to happen, but every attempt is not only hard to use, but also used for very illegal/immoral stuff that makes it the target of regulations, preventing it from becoming popular. And even if it ever reach popularity, it can cross a threshold making it full of trash like the previous medium, and we would have to restart again. Maybe we should create a system that is hard to get it, to prevent people that are not interested enough to come and trash it.
