@hschmale @Tutanota I don't think you'll find what you're searching for here.
Don't get me wrong, there are some people doing that, but I feel this is not a good place for such things and the vast majority of users don't use this social that way.
A better place to find such things are blogs.

Here I appreciate the community building process and the societal development. It's not people following other people but rather creating meaningful relationships with other users, getting to know them and discovering what springs from common interests.
Generally, I interact with a few groups of people whom I share something with and only rarely I get to write things for the general public.
I do sometimes write extensive analysis on some topics, but these are generally in a discussion with somebody. As an example: I am a chemist and some time ago there was a discussion about the methodologies to deal with tear gas; so I helped them out by performing a literature review on the topic and providing them with extensive information about the different types of tear gases and possible remedies.

You give to other people and get from them.
I try to keep the amount of people I follow small, as that helps me to have a cleaner and more explorable home timeline.
