[Hac-announce] link to Dan Ariely TED Talk

[Manny Ratafia]

At today's discussion of Dan Ariely's book "Predictably Irrational," I 
promised to send out the link to Ariely's TED talk. This talk was 
originally brought to my attention by Carol Siddall. I found it 
interesting and entertaining. I hope you do too.--Manny
