I think the link to the article and the publication is appropriate, and I would do the same.

I visited the “What Trusted Advisors Do that Others Don’t” and noticed in the sidebar on the left that the link to your web site still uses your old branding with the ink blot.

I think linking of words is appropriate when they are technical in nature, as this gives the reader an easy resource to consult if it is an unfamiliar term without providing unnecessary explanation in the body of the text for someone who is au fait with that term.

I also agree that one should not over-link, as that can become overwhelming.
