I have been playing with Frappr! the google map mash-up which has really caught peoples imaginations. In some ways it combines mapping with sites like friends reunited or friendster which create and join up online communities.
This is really powerful stuff, it may sound very geeky but finding out there is someone doing the same conversion on their MGB as you in the next town, or looking at the destination of pupils of Downfield Sixth Form of 2000 is really interesting – this makes geographic information really accessible to people – and who knows offers the potential of a mechanism for community data capture projects.
