OpenStreetMap
I just had to get BT747 working on my Mac so I could upload some of the GPS tracks I had taken at the weekend with my Holux M-241.
And then, of course, once they were uploaded I just had to go and trace and name them - and correct a number of serious errors in the northern part of Burgess Hill in Sussex, UK. There is no Yahoo! imagery here, so track & trace it is.
This OSM lark is addictive, and I'm going to be tired at work tomorrow!

That reminds me of when I first discovered OSM. It was pretty late at night: 23:00 or so. I just had to enter some data that night, so I went out for a cycle for about half and hour then got back and started entering data (whilst having to do much learning) into the small hours. I'm glad you're finding OSM addictive!
