Thanks for the reply Theymos. The decade long experience in moderating one of the most volatile and dynamic communities speaks in your post above.
Theymos and his crews have been able to achieve one of the highest level of moderations on the internet, while keeping the spirit of freedom of speech alive.
I think that the whole concept of discussion has degenerated a lot over the last 10 years or so. People are increasingly stuck in cesspools of groupthink, often on platforms like Reddit, Twitter, and Facebook where it is very easy for companies to manipulate the group's thinking by exploiting flaws in the platform. The Russia-Twitter thing is making news now, but that exact same sort of thing is being done constantly, on all subjects, and on all major platforms -- often for for-profit reasons, but also sometimes for political and/or nefarious reasons. Meanwhile, traditional "trusted sources" (eg. news outlets) are nearly all incredibly biased and clearly uninterested in the truth. It's a worrying trend.
Maybe the existence of "champions" is sort of a crutch that people use to get some truth when everything else they're looking at is garbage. 99% of what you hear on the major platforms is false, so you have to have someone you consider trustworthy like eg. Andreas help you filter the signal from the noise. But while this is better than just exposing yourself to the raw noise unguided, and I would not discourage knowledgeable people from acting as champions, it is a point of trust/centralization. There's also the problem of how your trusted sources are themselves supposed to reliably arrive at the truth when they're also surrounded by garbage all the time; they'll have the advantage of knowledge, experience, and some high-quality connections, but it's still difficult.
I wish that I had a fool-proof way of solving the underlying problems of discussion and truth-finding, but I only have some ideas for making things a bit better, not a complete solution.
That said, I agree that it would be beneficial for more people to create more good information and guidance.
(BTW, when talking about decentralization, you have to keep in mind that the complete elimination of centralization would be a dystopia in the same vein as Vonnegut's Harrison Bergeron. You are the sole central authority of your own thoughts/feelings/actions/statements. Some people have a harmful knee-jerk reaction against pretty much anyone doing anything because it is "centralizing".)
For me it coincided with the arrivals of the "kevins" of world of warcraft (first time those peons touched a computers) and all the sluts of facebook (who always saw computer interested persons as shit (pc word : geeks). And then here on BTCtalk it's fun to watch all the hordes of 3rd worlders all trying to gain from sig campaigns writing shit most of the time, and sometimes exposing the deep cultural divides that exist in their ways of thinking...
People are herded to those centralized and controlled platforms by the complicit and treasonous medias wings of those organizations. How many times have you seen a so called reporter quote bitcointalk? one of those intellectuals or academic sellout quote bitcointalk? Never ! Like the leeches and traitors and enemies of mankind they are, they can't even refer the source of where they really find "their" new novels ideas.
I don't think there are flaws, but design features, to herd, to cattle, to shepard the gullible to the slaughter house, where all form of oppositions is censored, where all news ideas are leeched and where selected people are chosen to "succeed". All a giant scam.
The traditional news sources died when they decided to follow the new world agenda, I can't find the quote but it was some kind of bilderberger or ... I found it :
DAVID ROCKEFELLER THANKS MEDIA FOR ITS SILENCE
-- David Rockefeller, Speaking at the June, 1991 Bilderberger meeting in Baden, Germany (a meeting also attended by then-Governor Bill Clinton and by Dan Quayle--
"We are grateful to the Washington Post, The New York Times, Time
Magazine and other great publications whose directors have attended
our meetings and respected their promises of discretion for almost
forty years."
"It would have been impossible for us to develop our plan for the world
if we had been subjected to the lights of publicity during those years.
But, the world is now more sophisticated and prepared to march towards a
world government. The supranational sovereignty of an intellectual elite
and world bankers is surely preferable to the national
auto-determination practiced in past centuries."
by: David Rockefeller (1915- ) Internationalist billionaire, CFR kingpin, founder of the Trilateralist Commission, World Order Godfather
Date: June 1991 Baden, Germany

A great Champion is Peter Studa from bitmessage, specially following the recent remote execution injection attack that BM experienced. Even if he certainly isn't the most talented coder out there he seems to have worked his ass to make bm safe again ! He was able to organize the recoding.
thanks for your post theymos.
