Looks very decentralized 
 This would compare favorably with a map showing where the handful of mining pools are that control 99% of the hashing.
 
 I really do like it  

I will be a buzz-kill and ask what the map with the locations of the developers looks like  

Or the size of the BTSX balances on exchanges like BTC38  

Unfortunately decentralisation is only as effective as the weakest link and BTSX is still 3 months+ away from not being incredibly centralised.
