A fun side-story: There was a question on Quora recently - "Why did Duck Duck Go Block Mahalo.com?" and Jason Calacanis, of course, felt it necessary to weigh in. I had to read this response twice, assuming there was some intended irony:
"if they did that is a big mistake... we are not close to spam and a we have the best articles on many things like how to play guitar, speak french, etc."
