If every second word on site was a link, nobody would bother to click them. People would just be frustrated by all that blue words.

Hmm, maybe that's argument for making different categories of links. Like blue links for things you suggest to read, light blue for things that are relevant, but not that important for most readers, and gray for links to definition of a word, source of the data, such things, that most people would ignore.
