Google Strategy

Google folks really are great businessmen rather than technocrat nerds. I guess if Gmail was launched without inviting the choosen few for beta testing, even tough its free and offers 1 GB, it would just had become a secondary dump of attachments for most. But superb strategy, having gmail has become a matter of pride. You are among the choosen few. And capability of inviing others :). I think before starting the service publicly Google would make millions of ACTIVE users. GREAT BUSINESS PLANNING.
