What's Interesting About Twitter?

I am wondering why people scream for privacy when it comes to Google's way with dealing with privacy issues and not do the same for Twitter?



What exactly is the difference? Is it that you only post what you are up to according to your feeling of privacy for that moment? I don't think so.



I also wonder what is the difference between Myspace and Twitter?



Isn't Twitter another way of giving up on your privacy?
