I'm almost afraid to ask. What is marchingstuck?
(With reference to this post here.)
Okay, strap yourselves in, folks…
For those who don’t remember the Dark Times, at the height of its popularity, Homestuck had spawned several fan-created AUs that were, themselves, popular enough that people unconnected to their creators would write fanfic set in them, cosplay as the AU versions of various characters, and so forth. It got to the point that some of the most well-established AUs had separate mini-fandoms made up of folks who’d never actually read Homestuck proper, and were in it just for that AU.
The most prominent example of the type is probably Marchingstuck, a high school AU in which the Beta kids and Alternian trolls were all members of a school marching band. (The Alpha kids and Beforan trolls don’t feature because the whole AU lived and died prior to their introduction.) Marchingstuck was so popular that it went recursive and spawned its own fandom project, a Tumblr-hosted fan-fan-comic called Promstuck that ran for six months in the latter half of 2011 and successfully concluded after over 250 pages.
(I was never into Marchingstuck myself, though I did casually follow 4chords for a while.)
