Salmon: Journalists should link to sources, but don’t expect readers to click
“The simple fact is that even if people can follow links, most of the time they don’t. An art of writing online is to link to everything, but to still make your piece self-contained enough that it makes sense even if your reader clicks on no links at all. …
“In general, it’s good to link to as many different people and sources as possible, because the more links you have, the richer your story is. On the other hand, the journalistic web is full of garbage hyperlinks — automated links to irrelevant topic pages, for instance, or links to an organization’s homepage when that organization is first mentioned.”
