Great article Jennifer!
Crimson Fox, I couldn't agree more, sometimes we take the "keyword rich anchor text links" mantra too far and forget that it's people with VISA cards clicking links and spending money, not bots.
On the other hand, giving up link popularity opportunity isn't good either, the value behind the right verbiage is like money in the bank.
I think it's safe to say most people know that different colored, underlined verbiage on a page means that text is a hyperlink. Where this gets to be a problem is when the verbiage isn't aligned at the end of an informational paragraph or in a logical location.
Hyperlinking text in the front of a sentence and not doing so again at the end could result in a prospect losing interest or focus while reading. Consider keeping the links at the end of the sales pitch, or within the flow of the information so it's a natural reaction to click and move on.
