that W1U is part of a postcode used in the UK, specifically in London: http://www.postcodearea.co.uk/postaltowns/london/w1u/
I have a twitter search for WIU, Western Illinois, or W1U and posts about events and things going on in London occasionally pop up in there.
Something random that I've realized lately...
