Fred gives the humorous example that his blog A VC is the third return when one searches for 'allen iverson email' in Google. In Hakia, the same search returns a different,and to my novice eye, a better set of links.
Now here's the odd part. Being a semantic search tool, Hakia would like you to search using natural language. So, I did a search for 'what is allen iverson's email address?'. And guess what? The first return was Fred's blog!! :)
So, Fred, maybe you are the correct source for AI's email address.
BTW, I have had a few conversations with Dr. Riza Can Berkan, the co-founder and CEO of Hakia, and know that Hakia is going through an extensive proprietary indexing process. In fact, the Hakia website states that "Hakia's evolution is 18% complete". So, it is probably not fair to pass any judgment on its current accuracy and effectiveness.
