Well I guess it is simply "Something that reads like a heavily illustrated novel.". Not much more. It is delivered in small pieces and have a community interaction with the story.
Well that's not that exciting or even new. I don't know of other countries, but some of brazilian literature classics from the XIX century were originally published in small pieces at daily newspapers. With intense debate around the paths of the story.
"Manipulating" communities is nothing new either. Art is not that vanguard when it is doing something that companies have even a career path for people who "manage communities".
It is so obviously a fan review. But that's ok, it was an interesting reading.
Where I think it gets right after reading the review and a few searches. It is a piece of art that embody what the internet is, not what was predicted to be. No small feat, as there were a lot of hype about what art in the internet would be and no one seemed to get right until now.
Apart from Homestuck, I found incredible the insight that in the past we had to plant, cultivate and harvest knowledge, usually conforming to not get any. Nowadays we are in abundant forest of knowledge where we can just pick up anything from the trees anywhere.
Not sure of the consequences of this shift, but an awesome insight about the internet era that I never saw before. Really worth reading it all if just for it.
