Good to see that Tim and Nigel have been making the most of the opportunity offered to open up the govt data - very useful for Horizon we should be watching these data sources eagerly as they come online to see what new and interesting applications they might enable. They have a column in the Times Online "Put in your postcode, out comes the data".

Right now I'd appreciate a map that allowed me to click on the street lamp outside my house and sent off email to whoever is responsible for fixing it :-)
