What to say about Bill. There's nothing to say about is immense knowledge on information retrieval, patents, SEO - it's something everybody knows; but the real side that let he shines is his personality and the simplicity he always carries with him.
I cannot remember any single episode where he didn't reply to me. I'm immensely grateful to Bill for his contribution to my interviews, events, speeches and, as an Italian, to review my first published English post.
Thanks Bill.
