On Android phone with Firefox, at least, that site seems almost perfect: all extraneous cruft removed, important sidebars intelligently incorporated, the main article text provided in nice readable reflowed form, and all other sections expandable but closed by default. It's easy to read and quick to navigate. I can't think offhand of anything I'd change about it.
