This lengthy article by ProPublica is about the FDA's faulty approval process of drugs available on the market.
I noticed something about the links in the article: nearly all of them went to other parts of propublica.org. This tells me that the website has done a lot of research on this topic, because all of their attribution is from other parts of their site. It also tells me, however, that all of their information has come from their website, which can present some bias.
The writers do a good job of embedding the links within the text so that it's not too difficult to see where they got their sources from. The writers didn't do the best job of web writing because of the massive amounts of text in the article. It's fine if there is a lot to read, but no white space made me feel as if I would never get to the end.
But, the writers also utilize the perks of web writing by integrating information boxes on the sides of the article, and enabling comments so that users can leave feedback or other information that might be pertinent to the topic.
