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 http://www.keyrelevance.com/ on keyword research using advanced tools at SMX. Top tips:
• Use http://stats.grok.se/ I continually forget about this tool but it’s ace for really detailed keyword research
• Also a great reminder about the recency attribute value pair on Google
• Matt Cutts on the canonical link tag
• http://www.mattcutts.com/blog/canonical-link-tag/
• Rand Fishkin on just about anything but specifically page rank sculpting
• http://www.seomoz.org/blog/google-says-yes-you-can-still-sculpt-pagerank-no-you-cant-do-it-with-nofollow
• Mark Mahaney http://biz.yahoo.com/a/1/137122.html on the future of the internet
• Mary Meeker on the state of the internet around the world from her numerous web 2.0 presentations
• As someone who led international paid search and affiliate co-ordination and all international internet marketing at facebook I think her analysis of which markets are the most advanced in different internet areas (esp. advertising and ecommerce) are very accurate from my experience.
• Sean Parker from the founders fund/napster/plaxo/facebook talking about viral loops
• if you ever get to listen to him on this topic it’s amazing… he has a really simple description (which I won’t spoil by sharing here) that helps you understand them extremely well.
