Reading Wikipedia is a skill
Many misinterpret what Wikipedia is because of lack of capability to read it properly. Unlikely what many see at first sight, Wikipedia is a complicated and sophisticated entity (and is popular moreover) so one must learn how to read it and not just take literally what is written. One must bear in mind that the text is multilayered and different pieces of it are written by different people at different times (reminder: all previous versions of each article are kept and can be read by anyone by clicking 'history'). It may be that an article has one main author and mixed additions of links, templates categories and so on. Sometimes it is clearly visible from the style, but there must be understanding that it can't be directly visible. That's how you may visualize it (different result every click).
