Quite an interesting approach to mapping, and it sounds pretty useful for the intended purpose. Conversely, I&#x27;m in the &#x27;Lazlo Hollyfeld&#x27; boat of wondering what the purpose might be for the actual goals of Facebook, which isn&#x27;t connectivity and internet altruism, but generating revenue. In this regard, I wonder what comes next, because looking at evidence of human activity will probably relay more rural and dirt-poor settlements than ones with disposable &#x27;leisure time&#x27; and monies.
