Archeologist, I have to disagree, at least to some degree. There is going to be a lot of people who hear of it from the first time, and led by curiosity, will also check out the comic and find the differences appaling.
And yeah, I can agree with the message just above. The kids do need some tweaking. Fortunately, the changes we're talking about are pretty subtle so it won't be that hard to change it or to even turn a blind eye to some things, which actually sounds like a Very Homestuck Experience.
