How can links be used to establish or extend an argument?

You can use links to support an argument in many ways. One way is to provide a link to a site where your reader can get more background information that will support your article. Or, links can provide access to another site in which that author is also arguing your case. You can also incorporate links into sections of your argument where you go into greater detail giving the reader the choice to read the details by linking to them or just skipping over them.

One site where linking was used correctly to help their argument is Bill Weavers homepage, where he clearly explains what all his links are.(The argument here is to use this page)

There are also many ways to use linking incorrectly, which will hurt your argument. You could put in links that are out of date or just don't work, and destroy your own credibility. If you don't provide enough information to where your links are going you may just confuse your reader. One way to avoid that is to make sure you don't only highlight one word and never use: to link click "here". Don't let your argument get too diverged through linking, and only link to relavent matter. And remember don't link to sites just because you mentioned them, only link if it will add relevant information to your case.

One example of where the links did not enhance the authors argument is Bill's Home Page where Bill linked on almost every word just for the sake of linking.( The argument here though most wouldn't follow it again, is to use the page)
