>>9636057...the use of troll in homestuck was a reference to the pre-existing term troll, not the source of it.
That said it still did, although less directly. A lot of big shitty twitumblr fandoms (DR, Undertale, SU, She-ra, etc.) link back to it. Undertale and any that branched off from it are obvious (Toby Fox mostly being known for being a composer for Homestuck before Undertale got big), DR and it's branches were one of the many fandoms that got big in that space because they happened to coincide with a homestuck break (in DR's case because an LP of it got popular at the time, pretty much directly leading to its localization.), etc.
You could see this happen in real time, back when it was running. All the Homestuck fanblogs would convert to the new fandom for a few months and then go back when it came back.
Now, Homestuck crashed and burned hard enough to have next-to-no current relevance for the work itself (and thank god for that), but you can link a lot of shit directly back if you know the history of the relevant fandoms. It's arguably all the same fandom "space" with how much they overlapped, although it's a bit of a Ship of Theseus situation with the actual people involved. Mostly, at least, some are still there.
