For those of you "Normal" people who aren’t all into the technical aspect of Google, Matt Cutts is one of Google most popular engineers. If you ever see him, he is one of the nicest and guys I’ve ever met. Also he knows ALL about Google’s search. He always answers everybody’s questions AND SMILES ABOUT IT! Although he and I differ on the idea of paying for links, I give him kudos to his mindset behind his choices.
btw Matt, if you are reading this I suggest that Google starts treating paid links differently. It should be similar to the way links from .edu are different from .com
