Here are just a few points taken from Barry's excellent coverage of PubCon:

• "SEO is not spam, its only when you go against guidelines, when it is spam."
  
  
• Redirects: "We are working towards a framework where we are indexing the destination."
  
  
• "some things in the algorithm that may be perceived as a sandbox..."
  
  
• "Splogs are bad."
  
  
• "Google does not have the ability to hand boost any site, or hand boost any pagerank."
  
  
• "Matt uses ancient versions of Netscape..."
  
  
• "...positioning text at top or bottom, is over rated."
  
  
• "Best links are earned, not sold or traded."
