OpenStreetMap
I am really surprised nobody mentioned yet there was changeset number 20000000. The guy behind is newcomer cosmicpop who one-wayed the Horace Road in the Eastern London. Congratulation!
And for the rest of us: open your favourite kind of drink and celebrate :-)

Woohooo! This is pretty exciting. Already 60k changesets happened since then. I think it is important enough to make it to the news on the wiki. Do you want to add it? http://wiki.openstreetmap.org/w/index.php?title=Template:News&action=edit

Well, I am not sure if this is so important. And even trough it is I don’t feel like being the right person to do so. If you like to feel free to do it! ;-)
