@Aral Balkan  It's the difference between "I want to be famous" and "I want to be part of a community."  

In the past, forums and discussion groups were great for building communities, but were not federated, so they had limited reach. We also had blogs and RSS feeds but you needed SEO to be seen. Then social media appeared and gave everyone a soapbox to stand on, and people shouted into the wind hoping people will notice.

Now, we have an interesting opportunity to bring back communities and blogs, except federated this time. Hopefully we can marry the best of both worlds, and avoid bringing over the more toxic design elements.
