My posts to the Reader blog often have screenshots, and I'm pretty picky about what goes in them. It's nice to see that others have noticed this too. My most recent post has a link to Dinosaur Comics, which the author seems to appreciate. Similarly, I intentionally left a reference to Valleywag in my trends post, which they noticed.

In some fashion, Apple does this too. A patent of theirs had a BBEdit reference, which amused the author of the software.
