Platial member Veehikle has a blog called T3 Consortium's Scratchpad of Thoughts. So far he's using it for great mapping projects. The first one is a map of historic pubs in New England and the second one is America's best burgers. (I see some kind of theme starting here.)
Both maps are open for submissions, so go and give your favorite burger joint its rightful place on the map and if you see a pub missing, put it on there.
I love the way he's using the new flash version of the maps in his blog posts and I also like how he changed "Steal this map" to the more polite "Borrow this map."
I'm excited to see what he's going to map next.
