How many Google Subdomains do u know??? The answer may be 10-20 (of course if u r not Tony Ruscoe)
Tony has maintained lists of Google external as well as internal Subdomains… You will be amazed to see such a long list with updated by him continuously. A Google Addict (as he seems to me) also maintains list of Google Account Service Names… As a Google Lover I really like going through these listings. Hope you will enjoy too!
At ResourceShelf you can also find a List of Googles Subdomains as well Directories.
