Some day I may have more than three readers and I can take a look at blog statistics like Aidan does. In the meantime, I will have to play with online geography games and such. My favorite is here. I have not made it to the final level yet, only through level 11. Yes, I know the map is small and it's hard to be accurate, but it's still really easy to be a thousand miles off...so it's a trade-off.
Other fun geography related places to visit are StrangeMaps as well as this GeoQuiz site.
