So both bitcointalk and r/bitcoin is administrated by the same person but with entirely different agenda with those sites.
I think the reason mods are so much twitchier there is because of that upvote/downvote horseshit and all the possibilities to fuck with the perception of threads.
On here someone writes some shit, other people call them a prick or ignore them. That's about it. Reddit has far more possibilities to undermine and reframe things, not that I see why anyone should care. I loathe Reddit as a format.
