Nmap Operating System Survey

For fun, I decided to test out the new remote OS detection capabilities of nmap to find out what OS was running on popular Internet security and educational sites, as well as a few sites of general interest. Later I decided to compare the nmap results with those from queso, another OS Fingerprinter. I have also added my own obnoxious comments :).
