Amazing Speakers I have heard recently

I wanted to share a little list of folks I have heard talk recently (online or in person) who I think are totally amazing and worth listening to:

• Christine Churchill on keyword research using advanced tools at SMX
• Matt Cutts on the canonical link tag
• Rand Fishkin on just about anything but specifically page rank sculpting
• Mark Mahaney on the future of the internet
• Mary Meeker on the state of the internet around the world from her numerous web 2.0 presentations
• Sean Parker from the founders fund/napster/plaxo/facebook talking about viral loops
