Alex Bellos is a freelance writer and broadcaster who lives in London. He's the author of "Alex's Adventures in Numberland" aka "Here's Looking At Euclid ".
His latest project is favouritenumber.net, an internation survey of people's favorite numbers and why. Since going active in May 2011, the site has received thousands of responses. Alex will keep the site open until September/October, maybe.
According to Alex, "as well as asking people to give their favourite number and describe why they chose it, I also ask where they are from and their age and gender".
Seems to me this is exactly what the www is all about, global chit chat.
