I looked at an article called "High radon levels persisted in basement where Ann Arbor police officers worked, records show" that I found on the nicar website.
There are several links throughout the article that lead the reader to websites with additional information. For example, one sentence discusses the radon that was present and it is also a URL to a site containing information about radon and how to be safe and preventative. The next couple links in the article are placed in paragraphs of two men who died because of the high radon levels. When the reader clicks on "died April 6" it brings up an article all about that man and what happened to him. Other links contain information and data that are relevant to the story.
This reporter would have to know some basic HTML in order to turn sentences into links with URLS. There is also HTML used to make some sentences bold or different colors. The reporter would also need to know how to use a blog, upload photos, and organize all of that information.
