Curate, connect, and discover
Not to be controversial, but I do think it's quite silly to knock on Homestuck: Beyond Canon for having references to internet memes in it, saying that this will "inevitably date it", and calling that an inherently bad thing. I understand if that's just not your personal taste, modern pop culture/online culture references is definitely something that will turn a lot of people off, but... Homestuck itself was filled to the brim with those same kinds of references. It's truly just keeping in the spirit of the original work, people only find it jarring now because they aren't experiencing it in a state of being a beloved time capsule.
Homestuck, as a piece of fiction, is fundamentally extremely derivative, referential, and reactionary, completely chock full of inside jokes and references to at-the-time modern media and memes. The level in which HS2 is engaging with current memes and media is honestly substantially lighter than Homestuck itself was. During early Homestuck in particular, it's difficult to go even one page without some kind of reference being present in it, especially considering a major point of the setting design and character writing is their relationship to other media. The posters on their walls, the games they play, the fact that Dave is living in a Saw trap, et cetera.
I find this train of criticism to be particularly fascinating, as to me it shows that, in some way, it doesn't really feel like a lot of people ever look at Homestuck as something that was ever new. The time period it was made in is almost never taken into consideration when analyzing the work. Homestuck never was, it just is. HS2 has current-day meme references because it is a current-day Homestuck story. This is exactly how things should be. This is just how Homestuck is.
