This seems like another case of the web development industry (in general) "fixing" "problems" that aren't really serious problems. I don't know of any user who would be confused by simply being at the bottom of a web page. I didn't look at the code, but my guess is it's a lot of Javascript spending cycles on my machine to solve a non-problem.

I suppose the article author disclosed right away that it's "overegineered" so maybe the post is more of a joke or exercise in absurdity? Nobody would really spend time doing this for a real project, right? RIGHT?
