Linking within news stories

Responding to Paul Bradshaw's poser: when writing for the web do you think you should include links within an article, or leave it till afterwards?

Well I'm not sure there is a completely fail-safe right or wrong way?

Links within the story make logical sense, as adding them at the end may mean the read has forgotten their purpose or relativity.

Although linking at the end lets the reader read the story without distraction.

But if there are no links, then the stories become dead ends on the website, and that page becomes an exit page rather - BUT the external links take users away anyway?

On our site we add related internal links and useful documents in clearly spaced blocks either at a pertinent point near the top or the end of a story. But specific relevant links go within the flow.
