If you click through the link to the website (instead of the PDF) it starts you off on the first page of the comic (not the introduction) with no indication that there are earlier pages. Which means it starts off sounding like it is something Scott McCloud wrote.
Leah Elliott
Contra Chrome
... a little down in the address bar:
"Remixed from Scott McCloud's Google Chrome Comic"
Next page: Again "Leah Elliott" and "Remixed from..." notice.
So the actual "remixer" isn't hiding or anything.
On the actual webpage, there's an "About" link, which is not hidden or anything either.
