The first link will be clicked on the most, the second link much less, the third even less etc. (Of course, there's other factors in play here, but that's roughly correct for a typical post, at least on this type of blog... e.g. Boing Boing has a different linking style where the last link is the most important).
And those first-link clickers also only tend up to be a fraction of those reading the blog post (which may itself be only a fraction of those who read the post's title, e.g. in RSS readers). And of those who read the post, only a small portion will write a comment.

In other words, the further away the "thing" is the more the attention drops, and the more it requires action, the less likely that action will be. This, of course, is not a one-directional thing -- the link to Google Blogoscoped in this post, I assume, will only be clicked on by a small portion of the readers of the post (other than it having value in terms of ranking on search engines, as we know).

That's why it's so important to create chunks of microcontent that will be able to live on their own (e.g. descriptive title), as well as making sure the first link is the "center" of the story whenever possible (in this case, I went for Daniel Brandt, who I suppose got something like 500 referrers out of it - dunno, but that's about the rate lately for Google Blogoscoped).
