While pretending that we hate it...
I did think that that is what you thought though. But to answer your question, I think it be pretty arrogant to say that some sort of dissensian idea was literally propagated from here and went out into the world. There may have been times when a hot topic was being discussed and we were kinda in parallel with other discussions and we came to what came to be the general conclusion so it could sort of feel like it originated here, but I doubt anything really came from here in that way. And, just imagine for argument's sake something did emerge like that, how on earth could it be proven.
So... from the forum I say "no". But you could say that books by K-punk, Dan Hancox, Barty went into something like the mainstream to a greater or lesset extent. The question is, did dissensus create those ideas - to which the answer is pretty much, also "no". But, I would say that those authors tested some or all of their ideas here to a greater or lesser extent and perhaps tinkered with them a bit, tested them a bit more etc
So, from dissensus -> mainstream not so much, but dissensus may have helped with the honing and shaping of some ideas that went mainstream-ish. That's the best I can come up with.
Unless someone would argue, say, K-Punk was on dissensus and K-Punk created the concept of Capitalist Realism or whatever, thus CR came from dissensus.
That specific argument may be totally factually wrong cos I don't know the timeline - but what I mean is, someone's could make that argument for any author x and their concept y who was on dissensus. Though I think that would be going too far.
