I was a couple of weeks ago giving a talk in Warsaw, Poland about Mozilla. I was followed by Vint Cerf, aka "One of the father of the Internet" (he co-invented the TCP/IP protocol). Being a fan, I managed to introduce myself after his talk, mentioning that I was part of the Mozilla community. Mr Cerf's response was very cheerful. I was told that he is a Firefox user and fan! Nothing could make me happier than these simple words from such a person.
