Right now the map starts centered in Europe - any chance you have the map initialize at maybe the centroid of each person's starred segments, or maybe just centered on one of them randomly? I don't have any over in Europe, so I've got to pan a bunch to get over to the USA to see mine.
Oh man, that's great! I like how the length and gradient come up when you click the pin. Any chance you can colorize it based on the segment's length or average slope?
