I don't think its unfair knowing how many influencers actually posted on this thread. Two people are known affiliates to the Fade To Mind / Night Slugs crew now and one became a DJ on Rinse; Goodman's already someone, we all know Ben Ufo glanced at the thread. They might've known prior about the music but I'm sure that the interest in the whole scene was granted a pulse considerably by this thread and perhaps other realms of communication. As someone who was watching this thread sporadically, a lot of y'all kept this thing consistently active when everything else fell by the wayside.
Seizing on something else you said though... I mean, not for nothing, a bunch of these kids if left to their own devices might've followed the DJ Nate model and gone on to make more hip-hop based music, and maybe one or two of them would've stayed making juke/footwork on soundcloud for a community that was small and hard to break. And fwiw now a lot of the kids and elders have a novelty value that keeps them feeling of importance for 'music enthusiasts'. On the one hand its great for them, but on the other hand a lot of it is influenced by working to the desire and the curation of benefactors, subliminally.
Its a cheap and odd distinction, but I feel like that a lot of the people you described aren't doing the traditional nuum activity of finding a genre and making it their home due to the genre they wanted to break into being overcrowded and inhospitable (the old grime/dubstep story of "we wanted to be junglists but it was already an established pecking order" bit), a lot of these other lot just got bored. I'd argue there's more nuum to say, the Kowton/Blawan/Untold-types going off to make weird techno stuff than these guys who reinvent themselves every year to whatever's trending.
"Oh Fly Lo-type beats""nah, funky house""Nah, juke""Nah nah, halfstep 'grime' ""nah nah, footwork influenced JUNGLE!".
Like, I don't need to insert names, you can pick whom could be an appropriate candidate for that sort of behavior.
What consistently happens is that the kids who these producers are inspired by/sign and sponsor sporadically while emulating/lose interest in have to end up figuring out if they want to emulate their world or redefine that to keep it interested to such a voracious and petulant market. Thankfully Planet Mu have done their absolute best to stay loyal to this scene and help work with the younger artists while curating the older artists but there's a weird disparity between the self-released stuff these artists might do and what inevitably gets released on a higher platform that suits the tastes of the benefactor. (Not a shot at Paradinas either, just he's in a weird mentor/appraiser role for some of these younger artists and invariably their careers get altered by his taste. Its no different than Goodman either) and so that resulting disconnect considering what media/press/whatever goes around the prestige label rather than the artists/genres who may not be thinking as consciously about promotion...
