I think the blue text works, but I agree that the green text doesn't. I originally had a white outer glow for all of the black text, but i got rid of it because it dominated the map too much. I've been playing around with the fonts a fair bit - i want something a bit fancy, yet clear. The smallest text is at 6pts. Originally it was bigger, but it took up too much room! Now it's about as small as it can go and still be basically legible.
