It was a mistake for Reddit to allow subreddits to set their own rules
I don't post at least 50% of the ideas and questions I would like to, because every time, I first think, are the mods just going to not allow it to be posted, after I write it all up, or if it is posted, cancel it?
The mods just make up "quality" or other random rules, and it just creates subreddits where no unpopular ideas are aired, and no non-mainstream questions or takes, because the echo chamber amplifies itself amongst what members thrive there and what tendencies are encouraged in them.
It would have been better if Reddit had set a couple rules, which it seems to have done anyway, and then forced all mods of subs to have open discussion boards, especially since there can only (especially when speaking practically) board for each theme, and one subdomain, which people often search their subject just by typing r/whatever.
