Ignoring the content of the article, why are so many articles on sites like these written so "weird"? There is lots of text and it seems there is very little actual content.

It is like only a few lines actually have something to say, but the rest is just filler content. It is like someone wrote an article of a few lines, and someone else just extended it with random sentences to fill a page.

To make matters worse, usually the page is also polluted with advertisements and referencing articles in between paragraphs.
