I hadn't heard about it until this post - I typed in 'where are you?' and got the response 'I live on the Internet' - Brilliant, a search-engine with humour!!!
I tried again with 'where am I?' and it told me I'm in London, my ISP provider and ISP address, then offered to show me a GoogleMap - That shows me as living in the centre of the River Thames between Westminster Bridge and Lambeth Bridge

(I'm actually a few miles eastwards of there

)
I've bookmarked the site, for more fun later - Thanks very lots
