When accessing mobile Wikipedia on my Nokia E51 all the paragraphs will be collapsed down with a show button next to the header, On clicking the show button nothing will happen.
Thus this is rendering the mobile interface useless making us needing to go to the full version which is very abusive on the screen space to access the content.
