I'll admit it. I am a font snob. So naturally, I find myself either enamored or horrified depending on what fonts appear where. When the right font is used and if all the visual elements fit together, that is a real piece of art. Which means, yes, I love to analyze and admire logos.
This site is pretty awesome. It has all sorts of articles about logos--their evolution, the principles used in making them, and what make them speak to us on a subconscious level.
Some articles I found interesting:
The evolution of the Starbucks logo

The use of negative space in logos (Who hasn't seen the arrow in the FedEx logo. Wait, you haven't?!)
