Ever since Google announced GMail, they have been the target for privacy advocates. A lot of people think that Google scanning their mails to insert ads is an invasion to their privacy. Big deal. First of all, every mail provider scans your mails. How did those Junk mail filters work in your opinion? Your mail can be intercepted at every hop that it takes before reaching the receiver's provider. Just try a trace route command once to see what I mean. Most providers like Hotmail & Yahoo! insert their ads in the body of your message. That is one thing that makes me sick of Yahoo! in particular. You want privacy, don't send plain messages. Use PGP, its free and secure. Encryption is the only way your mails will be safe. And I'd rather trust Google than some other company with my private information anyway.
