I don't think people understand or see a difference - they see just a link with content that they are interested in. It's the same with the ads one the Google SERP's: most people don't even know that they are ads and that someone has paid for it to show up there.

This may be true for some, but it's by no means a universal truth. I'm aiming to add to my site visitors education, and I'm assuming that many of my visitors are reasonably well educated people. That's certainly true judging by the content they visit and the patterns they follow. You can only fool that type of visitors once.
