Wikipedia looks like shit now. The lack of borders makes the page harder to navigate and the floaty sidebar looks janky and irritating in my peripheral vision.
You can still use the old skin though by appending '?useskin=vector' to the url, most conveniently by writing a rule in any redirector addon.
>Wikipedia articles will now have a maximum line width. Research has shown that limiting the width of longform text leads to a more comfortable reading experience, and better retention of the content itself. https://wikimediafoundation.org/wikipedia-desktop/
This is just terrible web design.
ITT discuss the new wikipedia layout and website skinning in general
